Will I be able to solve all math problems

>>100803747 fuck was meant as thread reply, can someone delete

>rule 1 >rule 2 >rule 1

huh this doesn't even make sense are you allowed to go diagonally or something? otherwise it's obviously impossible

>>100803851 it's possible

>>100803747 Only with the 0 seems impossible.

>>100803818 The second rule 1 is obviously part of the second line of rule 2.

>>100803818 >Rule 1: >Rule 2: >Rule 1

Chris you guys are retarded >You can use any mathematical symbol as long as it does not break rule 1 It's all one line you fucks

>>100803926 (0!+0!+0!)!

>>100803926 (0! + 0! + 0!)! = 6

>>100804200 (0!+0!+0!)! = 6 (1!+1!+1!)! = 6 square root of 4 + square root of 4 + square root of 4 = 6 Don't have the rest yet

>>100804200 / is not a mathematical symbol that's like adding an extra two loops to a 3 to make it an 8 this is either impossible or the person who made it doesn't understand math

>>100803747 >>100804200

>>100804359 >/ is not a mathematical symbol

>>100804302 Unless higher math states an ! is something entirely it's own thing. I'm assuming you're just adding a variable in, such as x or a. In which case your scenario still equals 0.

>>100804302 >>100804310 Well damn, thanks.

>>100804526 lol tard

>>100804526 What?

>>100804526 lol

>>100804200 > 5+5+5≠6 >not 5÷5+5=6 Why you gotta be so negative?

>>100804526 it means factorial

>>100804526 Underage faggot detected.

>>100804526 Are you serious?

>>100804526 Exclamation points in upper-level math means you shout the number, which gives it a higher value.

>>100804526 This site is 18+, and since you've obviously never done high-school level math I'm going to have to ask you to leave.

>>100804526 nice research faggot

>>100804526 Learn math before returning to the math thread.

>>100804526 somebody never made it past alg. 2

>>100804470 Yup this.

>>100804526 Top lel

>>100804359 >/ is not a mathematical symbol hahahahahahaha really

(0!+0!+0!)! = 6 (1!+1!+1!)! = 6 2+2+2=6 (3*3)-3=6 sqrt4+sqrt4+sqrt4=6 (5/5)+5=6 6+6-6=6 7-(7/7)=6 8 - sqrt(sqrt(8+8)) = 6 (sqrt9*sqrt9)-sqrt9 = 6 hope nobody beat me to it

>>100804470 >2-8=6

>>100804740 >|2-8| = 6

>>100804740 absolute value

>>100804740 >|2-8|=6 see >>100804526

>>100804504 i was talking about it in the context he used it faggot not as a division symbol also, this is doable. I misread it and thought square roots weren't allowed

>>100804740 He's got bars for absolute value around it mate.

>>100804740 Absolute value, bro.

>>100804730 I'm sorry breh

>>100804740 This thread is attracting faggots like there's no tomorrow.

>>100804740 Absolute value.

>>100804728 Adding a slash to a = isn't a valid answer, though.

>>100804740 He did the thing. Whatever it's called. Those lines. I can't remember. It makes it positive

Nice thread to find underage faggots.

>>100804526 hahahahaha it means factorial lol these posts are going to kill me

>>100804816 well, I'm glad for what it is. we differ in 8 but it's the same result

>>100804728 >being this retarded

>>100804740 Absolute value you mongoloid

>>100804794 inequality IS a mathematical expression dofus lol this thread

Wow you people are insecure I bet half of you people shitposting "HURR HE CANT DO MATH" probably sucked ass in high school/college, and are bandwagoning to feel better about yourselves

>>100804526 I like how you try to sound smart with your stupid bullshit.

>>100805008 But I learned factorials six years before sucking in college.

>>100805008 !^)

>>100805008 Hurt your feelings, faggot?

Math is gay

>>100804961 Wow dude do I really have to explain this to you The question states "YOU CAN USE ANY MATHEMATICAL SYMBOL" It doesn't say that you can alter pre-existing mathematical symbols Hence, drawing a slash through an equals sign isn't allowed by the rules of this game

>>100805069 I didn't even post the original comment bro Plus I'm probably better at math than 99% of this board I just don't feel like being a douche to people because it isn't there strong area

>>100804629 How high of a level are we talking here? Didn't see it all in high school. Does Canadian education suck that much?

>>100805189 OK, bro ;)

>>100805094 The rules didn't say we can't superimpose two mathematical symbols.

>>100804589 oh... >>100804590 >>100804691 Not underaged, just uneducated >>100804700 Welcome to /a/ >>>/sci/ math threads are that way. >>100804629 This made me chuckle!

>>100805008 nice damage control bro. but the fact 0! = 1 and 3! = 6 is common knowledge for the sophisticated users of this board, even for me who does mediocre in math

>>100805094 hahahaha This is the first time ive used this

>>100805234 If you shout a number with an exclamation marks, it is equal to 10. So 0! = 10 If you add another exclamation mark, 0!! = 10 x 10 = 100 And so on, and so forth. Meaning 0!!!! = 10 x 10 x 10 x 10

>>100805189 Ok.

>>100805540 and ?

I really dislike the square roots in 8 and 9 is the a way to do them without them?

>>100805812 aren't roots not allowed?

>mfw I don't understand any of this shit

>>100805905 That's what I initially thought it meant, but it means squaring, as in, to the power of two.

>>100805934 How young are you ?

>>100805812 I'm still thinking about a way to solve the last two ones, so meanwhile have this programming derp

>>100805812 yep, I did it with arcsin and arccos.

>>100806007 He probably still sucks on your mom's boobs so, pretty young.

>>100805905 Cube roots aren't allowed because they require you to write the number 3 which would break rule #2.

>>100805812 >>100806039 How does the exclamation point work anyway?

>>100803747 Can people post more of these now that this one's been solved?

>>100806417 but has it really? I'm not seeing solutions to 8 and 9

>>100806488 See >>100804470

Well. I learned something new today. Thanks /a/!

>>100805383 This integral doesn't even have any discontinuities for the given curves and you don't have to do a prime factor decomposition yourself, literally baby's first complex integral.

>>100806417 solve this: 0^2=0*0 0^1=0 0^0=1

>>100806518 wait, you can't square a number, but you can square root it? what the fuck? meh... "draw any numbers"; might as well just have written it

>>100806354 Just for you anon http://en.wikipedia.org/wiki/Numerical_analysis

>>100806577 Binary?

>>100806592 You can't see a number with the square root symbol >>100806577 You already solved that what would you want me to do?

>>100806577 there's nothing to solve, 0^0 is essentially a convention and for most purposes you should assume it as undefined

>>100806653 It's ok. I already switched it to english. I don't see what this has to do with factorials though.

>>100806665 >>100806698 Explain why

>>100806592 I think the distinction is that ^(-1/2) has a defined symbol. Squaring, or taking the nth root is disallowed because that requires explicitly defining a number, but a square root should be okay.

>>100806821 you inverted and negated the number, but your point was made

>>100806762 I'm going to go with 28cm^2.

>>100806735 It's already equal to something and you gave the correct answer, there's nothing to solve.

>>100806734 well factorial is nothing compared into what we use it, it's just one a the basics for the real fun.

>>100805540

>>100806762 28

>>100806873 How did you come up with that? What formula do you use?

>>100806874 But how do we explain it in reality ?

>>100806903

>>100806762 It's really obviously 28 cm^2

>>100806956 lol m8, you can do that in the blink of an eye

you should be able to solve this

>>100807015 >>100806949 >>100806873 Your answer will not be accepted without a proof.

>>100806735 In e.g. combinatorics it's useful to have 0^0 so the binomial formula, amongst other things, doesn't need special cases for 0. However when you take the limit of exp(-1/t)^t for t -> 0+ you get 1/e, which is obviously not 1, although lim t->0+ t^t = 1 and lim t->0 exp(-1/t) = 1. Basically, as long it's discrete it's reasonably safe to assume 0^0 = 1 (exception would be d/dt x^n = nx^(n-1) which obviously doesn't hold for n=1); otherwise consider it indeterminate

ITT: OP gets anons to do his math homework

0=0=0=6 others reduce to problem solved above

>>100807054 But how?

>>100807066 2nd last line, the x in 2x isnt the same x as the other x right from the equal sign

>>100807066 how does x^2 divided by x make 2x equal to 1

>>100807081 1=1 therefore 1=1 Or did you want a specific proof

>>100806762 Since it's only a draft and you can't see any circles, it's no solvable. It could be anything.

>>100807338 nope because it's the right answer

>>100806762 Kurisu is pretty damn good if she can draw that with a black marker. Has science gone too far?

>>100807066 the second derivative of x^2 is 2, not one

>>100807337 This guy gets it.

>>100807348 What geometric formula is used though?

>>100807402 who's talking about second derivatives?

>>100807337 >implying 0 0 0 are all the same symbols on the same system

>>100804470 square root should not count, since you're just using a different symbol to represent x^0.5

>>100807247 <what is derivative

>>100807424 Drawing a line from the median to the vertex to turn each of them into halves, then proceed to substitute. tl;dr do it faget.

>>100807535 here if you are too stupid

>>100807535 There is no way to know that these are really halves.

>>100807592 >>100807592 wait shit I fucked up

>>100807424 I don't know. I just googled it and some russian formula says it's 28.

>>100807066 work on your fucking notation anyway you're basically ignoring the (x times), write out the stuff in proper notation and you'll see it

>>100807674 shit, I'd really like the formula do you have a link to it?

>mfw never knew people on /a/ could be this smart Welp, might as well kill myself

>>100807891 Thank god I learned to call it "confront theorem"

http://en.wikipedia.org/wiki/Moment_of_inertia I still can't believe this stuff is more easier than it looks like.

>>100804470 There's an easier, far more simple solution. Rule #1 and #2 do not preclude MOVING numbers from row to row, nor does it state that all 10 rows must use 3 elements to create 6. Simple as hell to rearrange everything to always equal 6 with basic (+/-) operands. Checkmate.

>>100807973 >Not squeeze theorem. Which is what it is.

>>100807908 Oh nice.

>>100808063 different countries, different languages, etc. some people call it sandwich here too.

>>100808063 My teacher used to call it "sandwich theorem".

>>100807908 fuck, google can't translate it and most seem to have different answers

>>100805234 I live in Canada and I still saw this in high school.

>>100807891 >Mfw I learned the squeeze theorem in class yesterday

>>100807897 faget you want me to do math? fine. First of all they are triangles, therefore if you draw a line from the vertex to the median they'll be split in halves. I did not make this shit up, go take some geometry. second, do it faget.

>this thread >>100806999 >>100806903 A lesson of humility for me. I can't do all of that. m/ɐ/th is too strong, I go fuck myself in /sci/ right now.

>>100808203 Is it really true what they say about the Canadian educational system .

Let's make this more /a/ related http://www.wolframalpha.com/input/?i=miku+curve

>>100806762 Can you assume that the intersection point is in the bottom left quadrant of the figure and that the side lengths are integers?

Am I seriously the only one who was taught what ! was in middle school? It was at an american public school. Not to mention I live in SC where the education is supposed to be terrible.

>>100806417 Sure thing bro

>>100808352 I went to an american private school and I never learned that.

>>100803747 (D(0)+D(0)+D(0))! = 6 (D(1)+D(1)+D(1))! = 6 (D(2)+D(2)+D(2))! = 6 (D(3)+D(3)+D(3))! = 6 (D(4)+D(4)+D(4))! = 6 (D(5)+D(5)+D(5))! = 6 (D(6)+D(6)+D(6))! = 6 (D(7)+D(7)+D(7))! = 6 (D(8)+D(8)+D(8))! = 6 (D(9)+D(9)+D(9))! = 6 D( ) is the Dirichlet Function which will, in this case, always equal 1, since there are no irrational numbers involved.

>>100808274 Since he's a cunt, here's how someone else did it. >>98758353

>>100808151 We'll it's 28 so follow one of the methods that reaches that answer.

>>100808383 What does the "e" and hollw "n" mean?

>>100808352 I live in brazil and I was taught what that is in high school People here often talk that in america they teach derivatives and integers in high school, is it true?

>>100808352 Learned it in AP Statistics.

>>100808383 Didn't some japanese guy supposedly find the solution for this that's currently under evaluation?

>>100808333 Holy shit thats awesome.

>>100803747 You know there's a reason why I hate this bitch. This is one of that reason. Someone's already answered it though

>>100808442 That you're not going to be able to solve this

>>100808383 Let a = b = 1, c = 2^(1/n) (this works for all n in N). Try harder anon...

>>100808352 I never learned in even in High school, then again I never took calc. >>100808383 I don't think that's solvable unless you give me some values for a b and c. Like If I made them all = to 0, then n can be any number you want.

>>100808458 >integers I assume you meant integrals, and yes, depending on what math classes you take. Not everyone takes the same high school curriculum.

>>100808442 If don't even know this you won't be able to solve it anyway.

>>100808432 How do you know it's 28? How do you know the other answers couldn't be correct? fuck

>>100808274 you don't seem to get that you don't get two triangles with the same surface if you just connect two corners of a trapeze

>>100808458 It depends on the school and if you are in one of the more advanced programs. I learned calculus in my junior year of high school

I am not answering your problems until you answer my question. Why does worse girl always win?

>>100808274

tfw bad at math

>>100808383 Sadly over the head of people here. >>100808490 Not Japanese, although part of the proof relied on a technique some Japanese person invented I believe? It's already been proven years ago.

>>100808458 >People here often talk that in america they teach derivatives and integers in high school, is it true? Depends on what math classes you take. I took Calc my sophomore year of high school, but I was on an accelerated program. My sister, meanwhile, never got further than algebra while she was in high school.

>>100808442 You learn that in grade 9 math. You won't understand this if you're that young.

>>100808664 Oh whatever, I was thinking of the abc conjecture.

>>100808311 That it sucks? No.

>>100804302 >>100804310 I-isn't the result 0?

There are 5 mathematicians, 5 engineers, and 5 artists. How many distinct ways can they arrange themselves if all the mathematicians come before all the engineers. You may leave your answer unsimplified.

>>100808561 Because >>100808428

>>100808840 no

>>100808565 You can't be this retarded. A median does exacty this, split a triangle into two smaller triangles with the same area.

>>100808283

Did you guys know that if you differentiate the formula for the area of a circle you get the formula for the circumference? Like, woah, that should be so obvious.

>>100808761 You have a long way waiting for you

>>100808849 1. The artists wouldn't attend.

Is /a/ full of engineers?

>>100808565 You seem to misunderstand which triangles share surface area. This should help you out.

>>100808840 The factorial of 0 returns a value of 1. http://en.wikipedia.org/wiki/Empty_product

>>100808860 Yeah, I just remembered 0!=1 But I can't understand why.

>>100808849 (10C5)^2? aka 63504

>>100808924 But even if that was the case what about the arrangement of the 5 mathematicians and 5 engineers?

>>100808383 Define your a,b,c. Fermat's last theorem only applies for a,b,c in Q; in R >>100808502 happens and you look like an idiot (you are define your fucking variables)

>>100808855 the post linked in the post is deleted

>>100808849 I hate permutations. It'll basically be total number of ways you can arrange them divided by the total number of ways you can arrange mathematicians before engineers I believe.

>>100808937 Why else would we like traps?

>>100808981 don't worry, if you're not a mathematician, you have no reason to.

>>100809008 Nope but you are on the right track

>>100808981 because of the position that is cupping 0

>>100809051 and?

>>100808981 See >>100808974

>>100808981 It's just defined as such.

>>100808939 So, how dou you know, that the lines of the trapezes are the medians of the new triangles?

I think that is one way. I'm thinking of another that is much easier though. Hint: Figure out where the artists go first

>>100808939 question: is it actually a square or is it a generic rectangle. if it's a square this is easily solvable; for a rectangle not so much >>100808981 combinatorics.

>>100808937 I'm starting my degree in Comp engineering this year.

>>100809505 have fun, don't let the math crush you

>>100809319 How many are on the plane total? You never told us.

>>100809505 well for me it's electrical engineering

>>100809456 This is where the problem lies, seems like different countries have different conventions on this. Here parallel lines are marked with dashes.

>>100809319 Is this before or after they collide with the twin towers and the pentagon?

>>100808849 5!^2 * 15!/10!

>>100809620 Hooray, going for second year of mechanical This next semester, differential equations shall rape my angus

>>100804526 >Middle school fag Ban him

>>100809319 ALOT!

>>100809620 You chose more wisely, then. Both of you should study up on complex numbers, though.

Fucking lel at the people who try to make themselves better by insulting other people who made stupid mistakes Let me guess, failed high school algebra so you wan't to feel smart about yourself by picking on people at your same level online? Engineering major btw, I could probably wreck your autist ass at math any day

>>100809724

>>100808937 So am I the only chemistry MSc here in a math thread on /a/?

>>100809621 I've literally never seen any English source not use tick marks for parallel and hatch marks for congruence. http://www.purplemath.com/modules/conventn.htm

>>100803747 meh

>>100809750 I'm glad we know now. Thanks!

>>100809819 Rule 1 was violated.

I wish I could suck an /a/nons dick.

>>100809750 One thing is to be ignorant, but he went out of his way to try to sound smart without knowing high school math.

>>100803747 >>100803794 this thread is a fucking gold mine.

>>100809750 >Engineering major btw, I could probably wreck your autist ass at math any day As a third-year engineering student, I'm going to have to say that you're full of shit. A bit of calculus and diff eq is nothing compared to what actual mathematicians do. Unless you were really just bragging about being able to beat a middle-schooler, no, you're not that good at math.

Not sure if I'm the first one who thought of this

>>100809668 Yes. Good job! I'm impressed.

>>100809143 Is this hard for you?

>>100809813 Well we speak german in the part of Switzerland I live. And here it has always been that dashes indicate parallel sides. (Even now at University level). >wondering the whole time why people just assume lengths in the thread..I felt so stupid

Hint: picking on people who aren't good at math in a 4chan thread doesn't make you appear smart It just makes you look insecure and autistic Knowing the user base here, most of you barely passed the bare minimum of high school math

>>100809505 Hey thats me.

>>100809319 False. The Boeing 747 has 18 wheels. So the real answer is 54.

>>100809143 Here. If you still don't get it, I tried.

>>100809961 See this: >>100809969

>>100809942 That was actually right?

>>100808233 I Learned it my third year of high school. underage plz go

>>100809985 >Knowing the user base here, most of you barely passed the bare minimum of high school math This isn't /v/, smartass.

>>100809985 >doesn't make you appear smart This is a math thread, you can't just say something without definite proof.

>>100809985 That's some real projecting.

>>100809923 I've taken courses on advanced linear algebra, complex analysis and real analysis, and quantum mechanics, and I'm an engineering major. Why do you think they're mutually exclusive?

>>100804526 mods please ban under age.

>>100810042 Thank you. But my problem was this: >>100809969

>>100810042 So why do ou subtract the (B+C) part though? Rest of it makes sense

>engineering That prove that we have a good taste.

>>100810069 Yes. Now try it to where there are still 5 math, 5 eng, and 5 art but they arrange themselves so directly after every artist comes an engineer.

>>100810070 Squeeze theorem is a first semester university topic here in Germany. >>100810100 Wow, so much math and physics. You probably don't even know measure theory, stop trying to sound smart.

>>100808937 English major here, I don't know what I'm doing in this thread. I just like Kurisu

>>100810038 Nope, 58 is the answer. One Boeing 747 has 22 wheels for some oddfuck reason, but the others have 18 wheels. So, it'd be 58 in total.

>>100810100 >linear algebra >hard

>>100810170 Are all the engineers still behind all mathematicians?

>>100809985 No one's trying to look smart here. The ones who got picked were mostly the one who did so and failed terribly.

>>100810194 Just because you know the name of an area of math doesn't mean you're smart either faggot That's a grad level course, and I'm only 21 I bet you haven't even taken college math yet, and are just naming random shit to sound smart

>>100810246 no, different problem.

>>100810146 Because (A+B)+(C+D)-(B+C) = (A+B)+(C+D)-B-C = (A+B-B)+(C+D-C) = A+D

So I do Computer Science but it's a an MEng, as in Engineering. I'm so confused.

>>100810206 If you really like than become a engineer and build a machine that make her real.

>>100810285 >implying you aren't doing just that

>>100810227 Please tell me what linear algebra is then anon. Give me an example of the kind of things you do in it

>>100808892 Mother of god... At last I truly see. calculus is love... calculus is life.

>>100810227 And quantum mechanics which is basically applied linear algebra, easy as fuck. >>100810285 I'm 20 and I'll be taking an exam on it next month. It's an undergrad course for math majors.

>>100804504 dumbass

>>100810316 compsci is taught in the college of engineering at my university nothing weird

>>100810227 Matrices are easy only as long as they're full of numbers, and not arrays of other matrices. I swear that was the worst course I've ever taken.

>>100810227 It really depends on how deep you're willing to delve. >use your linear algebra knowledges to express the following conic equation (x^@ + xy+ y^2 + etc) >prove that given this specific subspace, the existence of a zero can also assure that the following... etc. etc. or even >prove the existence of the zero in a vectorial space

>>100810345 Find the null space of a set of equations.

>>100804629 I would give you half credit on that one for creativity

>>100810206 >mistyped everything in the first one. If you really like then become a engineer and build a machine that make her real.

>>100810288 10!*5! Maybe?

>>100803747 (0! + 0! + 0!) = 6 (1 + 1 + 1)! = 6 2 + 2 + 2 = 6 3 * 3 - 3 = 6 sqrt(4) + sqrt(4) + sqrt(4) =6 5 + (5 / 5) = 6 6 + 6 - 6 = 6 7 - (7 / 7) = 6 8 - sqrt(sqrt(8+8)) = 6 (sqrt(9))! + 9 - 9 = 6 Do I win anything?

>>100810042 Why do you just decide that those things are equal to each other? The As and the Bs and the Cs

>>100810356 IIRC, if you integrate the formula for the circle area you get the formula for the spherical surface

>>100810473 Not quite but you are close.

>>100810368 Quantum mechanics goes way beyond applied linear algebra I fucking hate it when people generalize like that It's a hell lot more interesting than linear algebra And also, linear algebra is still an area of research to this day It can become a lot more difficult if you don't just skim the surface of it

>>100810146 Simple, because (A+B)+(C+B) can also be written as (A+D)+(B+C). So for it to equal (A+D) on both sides you have to subtract (B+C)

Someone post the Ika thing please.

>>100810413 But who do I side with in the arguments between Science and Engineering?

>>100810423 Also finding eigenvalues and eigenvectors.

Guys, guys you are all fucking intelligent. I don't care if you guys know the surface area of your mom's vulva or the volume of the breast of the girl from the last doujin you fapped to. I came here to solve, not watch you guys show off how intelligent you are. Can we just please go back to solving stuff?

>>100810417 >linear algebra is about matrices >>100810423 >engineer level linear algebra >>100810420 zero is in a vector space by definition; even if you have to verify that axiom's consistency it's really trivial >>100810532 I was being flippant, i know it's way more. In the undergrad course I was taking it was basically some complex analysis with simple-ish linear algebra.

>>100810479 Oh and the first one is missing a factorial at the end, obviously.

>>100810563 Engineering Compsci is a lot more practical than physics or chemistry 99% of the research performed by your average physics professor is completely useless in the real world, and is only used to discover trivial things

>>100810646 Pretty much.

>>100810661 At least you can draw kuhwhy anime girls.

>>100810661 You haven't taken geometry? Isn't that like a middle school requirement?

>>100810661 You posted the answer.

>>100810597 > basically some complex analysis with simple-ish linear algebra My first course was like that too for the first half. Did you get to solving the hydrogen atom? That was by far the coolest part

>>100810719 What is this, the shinigami realm ?

>>100810597 >>>linear algebra is about matrices Well? My shit-tier professor told me so, but then again, he was so bad at teaching that I think our section never scored above 50, average, on any exam.

>>100810368 Finite-dimensional linear algebra is usually pretty easy, sure. But quantum mechanics involves a lot of functional analysis, which is a whole lot harder.

>>100810661 >haven't taken math beyond algebra 1 what Isn't algebra 2 and geometry required to graduate? confirmed for underage or retard

>>100803747 >Picture rules explitly says no squaring a number >Ppl using square roots >Y-yeah I totally did it guys

Stop blogging about your courses and how are you so smart for taking them. Post problems or solutions or go to >>sci/

>>100809262 >hurr How do you know they are not magnets?

>>100810737 compeng can do it too.

>>100810849 Didn't mean to quote OP

>>100810849 No adding numbers. When you write squares, you add a 2 superscripted. Square root signs don't have numbers.

>>100810849 >I don't know what squaring a number means Squaring is raising by the power of 2. There is no accepted symbol for it. What the rule says is that you can't write a small 2 above a number in order to square it, because that would be writing a number. A square ROOT has an accepted symbol and can thus be used. A CUBIC root can't.

>>100810857 There is a thread on /a/. What is the percentage of anons that are total and complete repulsive assholes.

>>100810709 That wasn't me. >>100810776 Uhh hold on let me find my lecture notes in applied physics we got as far as molecule approximations, in theoretical physics we went about as far with some stuff about entanglement etc. towards the end.

>>100810849 this post is retarded and I feel retarded for having read it

>>100810947 How else would they work?

>>100810821 >blaming the professor I fucking hate faggots like you Even if the dude is the worst in the world, at least try learning it. Also, linear algebra is about vector spaces. Not fucking matrices I highly doubt that the dude said that Sounds more like somebody who went to class twice and stopped showing up

>>100810761 Basic geometry yeah >>100810834 >implying I didn't drop out to get a job doing CA Tho, I wish I learned more advanced geometry and trig because oddly enough it goes hand and hand with art. So I am struggling to learn some things about art because of this.

>>100810966 Yes correct.

>>100808937 yes

>>100810849 Did you even understand the rules? There were only 2 you know. >No draw number >draw symbols but no draw numbers

>>100808892 No fucking shit, take a circle with radius r and a circle with radius r+dr, the difference in area for infinitely small dr will be equal to the circumference times dr, meaning that A(r+dr) = Circ(r)*dr+A(r), dA = Circ(r)*dr -> the circumference of a circle is the derivate of its area. Because for circles and spheres the direction of expansion of the higher dimensional quantity is always parallel to the lower dimensional quantity. >>100808937 Spacecraft engineer checking in.

>>100811024 >blaming the professor well, there are times in which we can't really help it at least here there are teachers that are only teaching so they can have the university fund their project you can try learning for yourself, but teachers are needed for a reason, otherwise books would be enough.

>>100810821 Linear algebra is about vector spaces and linear transformations. A matrix is just a representation of a linear transformation in coordinates, and multiplying two matrices corresponds to applying the two linear transformations in succession. If you only view matrices as arrays of numbers, you miss all the geometric intuition. (Plus, coordinate-free proofs are often much more conceptually clear and satisfying.)

>>100808937 Computer engineers and comp sci yes Who else is this pathetic?

>>100810942 I don't even have that much of a problem with off-topic, but this became a dick measuring contest.

>>100810963 I see. In all seriousness what are some of the more advanced features of linear algebra as to why people think it is so hard. I'm just minoring in math but i've take a few courses related to linear algebra and all of them have been pretty easy.

>>100810991 Idk could be a trick question

>>100810963 Then you probably did the hydrogen atom. That usually gets covered right before approximations begin. Approximations are alright but they aren't that rewarding. It's fucking cool when you find the wave function certain n, m and l, and your plot looks exactly like the stupid orbitals they discussed all the time in high school chem Spherical harmonics are also legit

>>100808937 Who besides engineer and natural science majors are pathetic enough to spend their evening talking about waifus with random people on the internet?

Is it me or does this board seem to attract STEM majors to it? Mayuri was the best girl

>>100811264 Me, I have nothing else to do. Waiting for death.

>>100808937 Physics and astronomy major coming through. I should probably take engineering courses so I can not waste my time on theoretical physics. Eat shit liberal arts majors

>>100811158 >geometric intuition >proofs Oh god, please stop. I can't handle that shit; I don't even know why the course was a requirement for CompE in the first place.

>>100811338 3d graphics

>>100810824 Yeah; we worked with infinite dimensional spaces but never had to do anything particularly complicated that'd require a functional analysis course. >>100811138 I found this out the hard way. Go to the damn class, even if it's bad or you fall asleep or get distracted. The only class where self-study really worked was where I understood the concepts by myself, which were like 4 out of 20. >>100811158 And then you get infinite dimensional vector spaces and your matrices vanish or become really unhandy >>100811253 Yeah I just said that in my post. >>100811240 Once the stuff you get is no longer intuitive. There's just different degrees of intuitiveness for people.

>>100811253 Not the guy you responded to. To me, quantum physics only really starts getting interesting when you start discussing interaction of light and matter, effects of observation, and generally multiple-particle Hilbert spaces. Not that the Hydrogen atom wasn't interesting, but I didn't find it all that fascinating and spherical harmonics are just annoying.

>>100811138 books are more than enough for anything, honestly It might not be as efficient, but if you put the time and effort in you can honestly learn anything. Sure, some people pick up things faster than others, but the people who say "I hate math, no matter what I do I just can't do it :(" are full of shit. They're just lazy assholes who don't even want to try learning it, and then pin the problem on something out of their control If they just tried to fucking learn it without be

>You have an egg >You are tasked to drop it somewhere two stories high >One storey is 25 meters high >You are given a bundle of straw, a bucket of water and a kilogram of flour How do you make sure the egg doesn't breaking after the fall from said height?

>>100811338 You'll need it. Linear algebra and calculus are huge parts of comp eng and without knowing at least those you might as well stop being in college.

>>100808937 Math major here, I don't know what half of this stuff means

>>100811444 I make a keeki with it.

>>100811440 but anyone can draw.

>>100811288 Because STEM is predominantly men in the age range that 4chan appeals to? They have the same demographic.

>>100811240 Finite-dimensional spaces are pretty straightforward, but when you get to infinite dimensions and add extra structure (topology, norm, inner product, etc.), stuff gets complicated (and interesting). Read up on functional analysis if you're curious — it's a cool field.

>>100811419 >interaction of light and matter >effects of observation Aren't those really fucking simple? Like that's what you cover in the first week of class And also, a "multi-particle hilbert space" isn't a real thing. Are you trying to say something else?

>>100811444 Why didn't you just say 150 feet or 50 m? You didn't specify bucket size, I'll just assume the bucket is 150 feet tall so I'll just drop it into the bucket.

>>100811440 You don't need $100,000 in education to draw dicks

>>100811440 Aren't most h-manga artists drop outs? I mean did a guy like fatalpulse go to university to better draw his mindbreak doujins. Even then actual artist majors despite being 90% fags are still superior to the other spectrum of liberal arts.

>>100811534 Thanks I will look it up when I have the time. I'm a computer engineering major anyways so there is probably some way that it may end up relating to it.

>>100811444 Break it before it falls.

>>100811158 That's all fun and well until you get into differential equations with linear algebra. I haven't met anyone yet who completely understands the derivation of the extended Kalman filter (which is commonly used in GPS applications). This miracle of linear algebra is pretty damn difficult to understand, and Geometric intuition really doesn't cut it here.

>>100811528

I've just got in CompSci and I can't even get past the first math course (Analysis) This shit is so fucking hard

>>100811557 Are you stupid or trolling? Interaction of light and matter as in the Jaynes-Cummings model and other related models, lasers etc. They are not simple (well they're not that difficult, but certainly harder than the H atom), and are covered in more advanced classes. A multi-particle Hilbert space is a simpler (and admittedly slightly less accurate) of saying that you're operating in a tensor product of multiple hilbert spaces, such as for multiple spinors.

>>100811466 >You'll need it. I haven't yet; literally none of the material covered has shown up in any other course. Most of what we do is actually practical, or at least grounded in the real world. Calculus has many uses, but abstract, higher-dimensional mathematics? Why?

>>100811756 I need it, but I've got some economy courses

>>100811557 He probably doesn't know what's he talking about. Effects of observation are the very first thing you have to learn in order to understand quantum mechanics. And he probably meant product hilbert spaces or however you call that in english (particle 1 in hilbert space H1, particle 1 in hilbert space H2, total hilbert space is H = H1 (x) H2)

>>100811769 what were you expecting? no one to be autistic?

Planning on going somewhere in the computational areas. What's the hottest thing right now? Computer Science? Computer Engineering? And for those who are in this area, is it fun and/or satisfying? What about money income?

>>100811794 No but you, for picking the two worst posts in a 420 replys thread.

>>100811769 I cant tell if you are impressed or disappointed.

>>100811829 I was expecting that the discussion would just keep itself to fallacious math problems coupled with a troll fest not algebra and quantum mechanics

You have a balance beam, the kind of scale that tips from one side to the other, depending on the weight on each side. On each side is a beaker, half-filled with water. The sides are in balance. Now, on the left side, you submerge a ping-pong ball suspended by a string. On the right side, you submerge a steel ball of the same volume as the ping-pong ball suspended from a crane. Challenge: Does the balance beam tip to the right, to the left, or does it remain unchanged?

>>100811849 Waifu engineering.

>>100811769 >tfw you've reported it several times but it made no difference T-thanks mods

>>100811718 Not that guy, but just be more careful with your terminology. Way too many anons here who just say stuff they read on wiki without actually understanding it to sound intelligent and inaccurate terminology is one of the signs.

>>100811338 Proofs are the road to enlightenment, and geometric intuition is your lantern.

>>100811769 I like these threads, it's impressive to see how I talk with such capable people on daily bases, you guys are the best. I still remember when some guy donated 10,000 to Little Witch Academia in some thread here on /a/.

>>100811649 Fuck that was pretty genius.

This thread never happened. I don't want to think I'm sharing this board with this mathematically inept retards

>>100811912 Same. Displacement etc.

>>100811912 Tips to the left, the steel ball doesn't actually have an effect on the balance beam.

>>100811849 Do CS and study AI so you can make our waifus real.

>>100811813 I do know what I'm talking about, and I mean 'effects of observation' in more technical terms rather than just the "intro to QM" way of teaching "it collapses the wave function and we're left with an eigenstate of the measured operator". As for the Hilbert space, yeah, that's what I meant. See >>100811718 I didn't want to start talking about Hilbert product spaces because I honestly wasn't sure everyone would get it.

>>100811962 >capable >tfw I know the material and do well on exercises but can't take exams/study for exams for shit so I have way too many courses I gotta retake.

I have never understood and will never understand people being elitist about their undergrad/masters majors.

>>100811849 Not sure, but really, be prepared at a fuckload of math. They're not there to teach you the basics of programming or something, get ready for things like graph theory, Turing machines, network theory, etc. I've seen too much people drop out of their engineering students because they didn't expect their second and third years to be filled with abstract math.

>>100811912 tips to the left, ez

>>100811849 I'm in computer engineering. Go to Comp Sci if you want to do application programming. GO to computer engineering if you want to learn how computers work and lower level programming.

>>100811756 if i do remember good, higher-dimensional mathematics is mostly used in encryption and all things related to it, which amke it of great important to comp eng .

>>100811958 Point taken.

>>100811912 tip to the left because the ping pong ball and string have weight, unless they're ideally of no mass whatsoever now, which is heavier, 2D waifus or dreams?

>>100811912 Tip to the right. The pingpong ball has air inside and will pull the beam up. Huehuehuehue

>>100803747 Let f(x,y,z) = 6 for all real values x, y, z f(0,0,0) = 6 f(1,1,1) = 6 f(2,2,2) = 6 f(3,3,3) = 6 f(4,4,4) = 6 f(5,5,5) = 6 f(6,6,6) = 6 f(7,7,7) = 6 f(8,8,8) = 6 f(9,9,9) = 6 What do I win?

>>100811849 I've heard that CS is bland and hard as fuck. Keep in mind that it doesn't really have anything to do with computers. CE is fun though, as long as you're prepared to cover a huge range of topics. And yes, you'll bring in the dosh as long as you can find a job.

>>100807460 factorials wouldn't count either then. also you can solve every line with the same method write each line as (0x)!+(0x)!+(0x)!=6 where x equals the lines number. you do have to shove your fingers in your ears and keep repeating 0 is not a number for this to work.

>>100812138 0 is a number, damnit.

>>100811912 Remains unchanged, both ball exerts a net force of 0 on the balance

How much programming is there to be done in CE? I'm great at physics and math, but I only did an entry level programming course and was shit at it.

>>100805299 Did you drop school at 10 or something?

>>100812095 no it tips to the right the steel ball adds weight in the right

>>100812173 It really depends on the University and the courses you take.

>>100812171 WRONG, 0 is just a symbol and can be associated with any number.

>>100811981 >A couple of retards fucked up >The whole thread is inept!

>>100812173 There is a fair amount of lower level programming. Don't do it anon. Go to electrical I would suggest.

>>100812017 It happens, some advice though, don't try to do too much at the same time. If you only have the time to study for a set number of exams, postpone the ones above that number, and ace the ones which you can do.

>>100812023 None of us are being elitist; we just talk with likeminded people about stuff we enjoy or at least study. >>100812016 I know what they're for, I know what they do, but goddamn they weird me out every time. Not having sufficient background before getting those dumped on you sucks. >>100812173 Do compsci. >>100812056 Wait, isn't it the other way around? In that case, poster i quoted above take compeng.

>>100811917 >>100812014 So be it, I will do it for you. >>100812024 I never had any problem with math, so I could probably pull it off. >>100812056 I would rather do application programming, but if what >>100812120 this guy said I'm not so sure anymore. I will do a little more research on it. Also, by low level programming you mean stuff like drivers, and native processor language? Could I develop H.266 on the future for Daiz?

>>100811849 This really depends because some universities do CS like Software Engineering and others do more on the low level side. I'll just finish my CS bac and do graduate studies on Electrical engineering to actually be able to build things from scratch.

>>100811661 Hey, still can't hurt to have a good geometric intuition for basic linear algebra. Sure, it'll only take you so far, but that's better than nothing (or viewing matrices as merely "arrays of numbers with a weird multiplication rule" or something). >>100811444 Walk two stories up, set the bundle of straw on the floor, then drop the egg onto the straw from a couple inches up. This is "dropping it somewhere two stories high"; there was no requirement that it fall the whole distance.

>>100812200 No dude, the steel ball has mass, attracts the beam, since there is no gravity whatsoever, and gravity is generated between their own masses I'm high dude

>>100811960 Proofs are, like, the opposite of intuitive. >>100812060 That sounds more like CS, or some kind of informatics, than CE. At the very least, it's a specialist field of CE, and not one that I plan on tackling.

>>100809277 Consider a square ABCD with a diagonal AC, creating two equal triangles ABC and CDA, calling the base and height of the two triangles BC,AB and CD, DA respectively. Now shift point A slightly to the right, keeping AB parallel to CD. This slightly shifts diagonal AC as well. Now, anon, the height and base of CDA remain unchanged, but the height of ABC, which is AB, has decreased, reducing its area. Place this example into the lower right region of the trapezoid, and you realize you need to fuck off.

>>100812173 Go study physics or math then. Pretty much any engineering study will have some programming in it still, but CE does have the most.

>>100812200 But the pingpong ball and the steel ball has the same volume.

>>100812005 >>100812172 Are right, the rest wrong

ChemE here, but I'm forced to take a circuits class, and I don't know jack shit about anything about circuits How hard are they/how fucked am I? Here's a picture of a question from one of my professor's midterms.

>>100812259 Some of the people in this thread are. But I'm referring to 4chan in general.

>>100812233 >0 is both a number and the numerical digit used to represent that number in numerals. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems. Sauce: https://en.wikipedia.org/wiki/0_%28number%29 Gonna have to disagree with you there, anon.

>>100812171 >>100812334 Numbers aren't even real, you faggots.

>>100812257 It's less of an issue with the quantity, although I had that issue too. It's just I get lost in all the material and then forget something trivial that really just takes a moment to look up in the lecture notes when doing exercises and you lose 20 out of 100 points on the exam because of it. I tried tackling it by redoing the exercises without looking at lecture notes or at least writing down what I have to redo but it's very time consuming (course in question was calculus 3, submanifolds of R^n, some measure theory, integrals in R^n)

>I can't into math past basic calculus >Proofs How do you not go nuts learning higher math?

>>100811912 The only force being exerted on the scale would be the displacement of the liquid correct? The neither the steel ball held by a string nor the ping pong ball suspended by the string should be exerting any direct force on the scale. Therefore there shouldn't be any change.

And here I am having barely made it through HS at 21. This makes me genuinely sad, I wish I was smart like you guys.

>>100803747 Answer this hoe.

>>100812337 what does the triangle mean?

>>100812369 How can math be real if numbers aren't real?

>>100812369 why did you even quote the second guy

>>100812334 >>100812369 Oops, meant to quote >>100812233

>>100812337 Thats just an OpAmp question. Remember, you can assume the current going into each enterence of the OpAmp is zero. You should be able to use nodal analysis to figure out the rest of the values.

>>100812337 That's pretty easy... if you know how Op-Amps work (assuming they're ideal).

>>100812425

>>100812389 90% of people in this thread are lying/bullshitting about the amount of knowledge they actually have For some reason people here believe that they gain magic internet points for bragging about their intelliegence Don't worry, you're probably as good as most of the people ITT

>>100812259 No computer engineers have to learn about computers from the circuitry up. Including the programming. The CS majors don't go into circuits at all. >>100812261 We have to learn machine code and stuff like that. Learn how to program micro controllers and stuff like that. The languages the CS people learn are easy to learn on your own if you are in computer engineering in my opinion. They learn more theory stuff, but once again that is easish to learn on your own when looking at it the other way around.

>>100811912

>>100812337 Basic op-amp, piss easy if you just pay attention in class. In fact, circuit analysis in general is just a few formulas used over and over.

>>100812381 Proofs are the hardest part about university level math. If you can't get an intuition for it, work with a tutor; that helped me a lot. Practice and look at our lecture notes to see how the prof did it. After that it's usually enough to look at the definitions of whatever you covered and you'll figure something out.

>>100812484 >believe that they gain magic internet points for bragging about their intelliegence it's more about self assurance

>>100812429 Yeah, misquoted that, sorry.

>>100812434 >>100812438 I haven't even started learning anything yet, I was just curious as to how complicated something like that was. So if I just understand how each individual component works, and do a bunch of practice problems I'll be good?

>>100812425 How can science be real if math isn't real?

>>100804504 He meant / as in the =/= does not equals sign

>>100812267 Of course, of course, it helps a lot with understanding things which are relatively easily intepreted as actual dimensional spaces, and particularly in attitude control it's applicable when you start getting into fun things with the orthonormal quaternion transmuted matrix (who the fuck invented that term), but it has its limits once people start linearizing and differentiating things like crazy.

>>100812574 How can computers be real if science isn't real? And this pulls How can 4chan be real if computers aren't real?

Couldn't you just mix in letters with + and - in there? Turn it into algebra?

>>100812425 But numbers are both real and imaginary

>>100811444 Drop it from three stories high. That way it would travel two stories down and stll wouldn't have been broken yet.

>>100812485 This is why I love CE, despite its including some shitty courses, too. >machine code >from the circuitry up >mfw

>>100812643 dude what

>>100812309 *Good* proofs are intuitive. Like the picture in >>100811960 — that's a proof of the Pythagorean theorem right there. Or Euclid's proof that there are infinitely many prime numbers (sketch: given any finite list of primes, multiply them all together and add one; the result isn't divisible by any of the primes on the list, so its prime divisors aren't on the list). A good proof makes it clear why the statement has to be true. What sort of proofs are you talking about, anyway? "The opposite of intuitive" sure isn't what comes to mind when I think of proofs. (Unless you're referring to those awful abominations known as "two-column proofs"? Those are a disgrace, a pedagogical disaster, and unworthy of the name "proof".)

>>100812537 Pretty much, if you can do algebra

>>100812485 Yeah, i think the best would be electrical engineering. They go up from scratch to how to make a full functional circuit with it's own programming language.

>>100812416 It's an opamp, in this question probably an ideal one, the idea is that it'll generate any voltage and current at its output port in order to force the difference between its input ports to 0. Very elementary component in amplifier designs, though I'd advice starting with nullors first.

Which course are most likely to build robots anyway? That's what I'm interested in.

I couldn't imagine doing compsci/eng I mean, I already spend all my free time on a computer If that was my job, I would spend 100% of my waking hours on a fucking computer screen My eyes would fall out of my fucking head Being a systems engineer is the best job ever I just get to walk around a college campus all day and make sure that everything is functioning properly, and force dirty laborers to do all the repair work for me

>>100812688 Like 0 + A + 0 + 0 = 6 (A=6) 1 + 1 + 1 + B = 6 (B=3) Sorry if that's retarded, I literally got 0 on my national mathematics test.

>>100812641 >mfw i'm reading posts that don't actually exist

>>100811912 Tips to the left very slightly due to gravity between the crane and right side creating a slight upward pull.

>>100812804 The forbidden cooperation of a mechanical engineer, a chemical engineer, an electrical engineer and a computer scientist.

>>100812651 No. A number isn't both real and imaginary (except for 0 depending on how you define the space of imaginary numbers which is a silly thing to do anyway). It's both real and complex, though. >>100812695 What's a two-column proof? In any case, he probably thinks that finding a way to prove something is counterintuitive which certainly is so until you practice it.

>>100812721 I've already taken thermo, mass/heat transfer, chemical separations, physical chemistry and kinetics I think I'm good lel

>>100812804 That's usually MechE stuff. Also possibly EE.

>>100807365 right answer is >>100807708 faggot

>>100812695 Yeah, I understood your image. A proof of something basic like that is fine, but a proof of something you don't even know to be true in the first place is just painful, for me anyway, especially if it's something that can't be represented in two or three dimensions. And then you're shown how it's supposed to be done, and the solution just looks like a bunch of blind leaps. Maybe I give up too easily, but it's a feeling like, 'What the shit, how did you expect me to guess that?'

>>100812867 Like he said

>>100812825 wtf man did you just not learn algebra or what? not being rude just curious

>>100812819 I did Information systems. The only part I use my Computer is to check my mails ones a day.

>>100807066 You forgot the +C.

>>100812804 I'd really go for extracurricular activities on that one. That's where I got most of my mechatronics experience (amateur rocketry is pretty cool, and we've got a bunch of aerospace and electrical engineering students). Aside from that, Electronics and CS have the most chance to encounter robots during their courses.

>>100812425 Decartes please, you don't actually exist.

>>100812935 he deserves the shame.

>>100812867 >chemical I have no idea why it would have anything to do with it and mechatronics exist don't they?

>>100812695 Not all facts have a *good* proof though. The proof of the Theorema Egregium is pretty shit...

>>100812804 MechE. But be prepared to be massively disappointed To get to building robots you need to go through years of solving differential equations and CAD modeling

>>100812967 not an integral

>>100809928 You had one job. Smart though

>>100812967 There is no integral there you fool.

>>100808274 I know this is old, but 16 + 32 - 20 = 28, which is the answer. This works because every side is equal.

>>100812960 What do you mean information systems? My kind of "systems" Is like water, HVAC, heating/cooling, and chemical treatment shit I'm a Chemical Engineer

>>100812985 Microcircuitry and things like a synthetic skin in a humanoid one.

>>100813016 Dont forget the matrices... Unless your program is shit and they have you playing with Lego Mindstorms or Vex shit.

>>100812960 Computer Information Systems? If that's it I ran the hell away from that one.

>>100813016 Achieving the goal is worth everything, even if it's worthless and not full optional.

>>100813145 It's half ComSci/Eng half economics.

>>100813150 >Lego Mindstorms I played with that once Man the software you use to program it is shit "Visual fluxogram programming, because why not?" Arduino is better on every regard. My folks also have a raspberry pi, but I haven't played with it yet

>>100813200 It's >>100813244 Well, it's in Switzerland and I had a lot of courses which I could choose from and was literally asked by 3 banks to work for them while still beeing in University.

>>100813225 I wish I had a goal. Right now I'm just studying phys/math for the sake of it and missing motivation is pretty annoying. At least education is free here (I wish it weren't, small classes where you have to attend and actually converse with the prof are way better than the 150-300 person lectures with small group exercises that don't go anywhere) (I know I'm being delusional)

>>100808937 Criminal Justice masters and Astrophysics Bachelors, working on Masters in physics.

>>100813320 Yeah, a bunch of graduates working in banks came to lecture about their successes and implementations of X security standards but the whole thing was too much BUSINESS and too little substance for me.

>>100813340 >150-300 person lectures Holy shit.

>>100812877 >What's a two-column proof? A terrible idea taught in many high school geometry classes in the States. Instead of writing out an actual line of reasoning that makes it clear what's going on, students are forced to use a "two-column" format with a formula on the left and an axiom justifying the step on the right. It's a completely inappropriate level of rigor for the course, and it drains all the intuition and beauty out of it and encourages formal manipulation of rules without understanding what's going on. (Pic related. Yes, it's really that bad.) >>100812998 True. But that's often because no one understands it well enough yet to come up with a nice conceptual argument. >>100812930 Yeah, coming up with proofs is hard, especially before you've developed a good intuition for the subject. (But writing lots of proofs is a big part of building that intuition, so it's tough starting out...)

>>100813340 >small classes where you have to attend and actually converse with the prof This only works if the professors are interested in teaching. At my school, smaller classes just mean that you get a bigger slice of shit. There's no winning.

>>100813440 I've had 500+ person lectures. Just depends on faculty size.

>>100813440 What so surprising about it ? aren't most universities like that ?

>>100813492 We have a lecture room for 500 or so people. I'm so glad that at my uni (RWTH Aachen if anyone wants to google) the physics faculty isn't as huge as the ME/EE faculty.

>>100812737 They make their own programming language? I've never heard of that. That is more of the CS and CE stuff. >>100812671 >mfw >>100812804 Electrical or computer engineering. Both majors are required to by the end of undergrad

>>100813440 My university's compsci lecture last semester had 1250 students enrolled

>>100812935 Back in my school days I thought I wouldn't ever need math if I have a calculator.

Any comp sci people out there? How necessary is math to programming? I know some linear algebra, and a couple courses worth of calculus, but I don't know them well. It's the kind of thing I could figure out how to look up, but can't do off the top of my head. Am I fucked?

>>100813550 no

>>100813440 >Course: Business Administration 1 >1300 students >4 rooms with showing live recording of the room where the prof was >podcast >half of the people failed

>>100813550 Not in the US from what I heard. >>100813653 To programming what?

>>100813717 >To programming what? a microwave

>>100813653 it depends very heavily on the types of things you plan on making. Writing a 3d modeling engine? You are in trouble. A vast majority of software engineering and problems? Think logically and you are fine.

>>100813717 The most at my US university is about 150 person lectures, well besides the sex ed class which has like 350ish. >>100813745 >yfw you realize microwaves have microcontrollers in them

This thread is suddenly making me glad that my school has lecture sections of about 30 people each. >1300 students

>>100809928 How successful are you in life?

>>100813704 >half the people failed yeah, i'm calling bullshit on that they wouldn't even do that at the most backwards school, unless the students are complete retards where was this at?

>>100813653 Depends on what you want to do. 3d graphics is like 90% linear algebra. For most programming you'll probably be fine though.

>>100813420 I don't do things like that, I just have meetings all day mostly negotiating and consulting with clients.

>>100813550 Really large powerful universities are like that.

>>100813875 The itt tech of Hoboken NJ

>>100813875 University of Zurich First year is about filtering students.

>>100813875 >ending a sentence with a propositional phrase

>>100813653 well from a scale of 0 to 10 i would say 100 let's say you want to make a photo editing program from scratch that can remove background, adjust colors and brightness and so ..etc you will get surprised how many math theories your gonna need.

>>100813986 are you autistic?

>>100814018 Hardly. You need a fundamental working knowledge of what they do. You're not in engineering to reinvent the wheel, just know how to search for other people's ideas and hope they aren't protected.

>>100813986 Nyaruko is the new Hitler of Grammar, or I'd say that if I didn't lose respect after that retarded tearful bed scene middle of S2

>>100813875 Eh, I've had worse. We had this course where only 25% of the people passed. Now to make it even more fun, this was the last course in the bachelor. And you have to finish all your bachelor courses before starting your master. This course fucked over so many people, and the teacher didn't give a fuck. This happened in a global top 100 university.

>>100814114 There was a season 2?

>>100813932 >>100813976 >>100814117 link to an official grade distribution? my school has all theirs online.

>>100813843 Same here.

>>100814117 Isn't this pretty common? >about 200 started information systems with me >only 17 finished got their bachelor degree

>>100814105 Pretty much this. As long you don't actually have to write algorithms (and then wonder why your shitty O(n^2) algo for traversing a linked list is slow) or actually do graphics stuff you'll be fine.

>>100814226 wait a moment, I'll look into it for this year

>>100814245 Not really. You have to factor in everyone who realized their degree would have been just as useful as a journalism degree and jumped ship. inb4 you started at 7 figures

>>100813986 >propositional phrase If you mean "preposition", English syntax has worked like that pretty much ever since it transitioned away from the Old English case system. ləɹn2hɪstoʊɹɪkəlːɪŋgʷɪstɪks

>>100814245 Can you please prove it with a grade distribution like I said in >>100814226 I refuse to believe myths like this At my school (which is one of the most competitive in the world) I'll always hear people saying "OH MY GOD MY PROFESSOR FAILED HALF THEIR STUDENTS ONCE, I'M SO FUCKED", and then check out the official grade distribution, which shows only 5% Fs People over-exaggerate way too much

>>100814420 In engineering at least most programs wont pass you with anything less than a C. C- is failing...

>>100814420 http://oecnews.fvoec.ch/wp-content/uploads/2013/04/OecNews_FS13.pdf page 21 seems like it has gotten better the last few years, but "Informatik I" note that you have to pass all courses here to go further

>>100814420 At my physics course pretty much every course had a 33% failure rate for the first exam except for a few. BSc Math was higher, Physicists's Math was lower. I won't post a distribution because I'm lazy and would have to anonymize but I actually calculated it because I failed a few courses and wanted to know how many others failed

>>100814420 Remember for some people A- is failing.

>>100814226 They don't post it online at mine, but I can access them. x out of 10 European system, 6 and above is passing. This study starts with 500+ people in the first year, in the end 160 or so graduate each year. It's considered the most difficult study at my uni.

>>100814339 It's one of the degrees where you statistically get most payed after graduation in this country. But people most likely drop out because they don't know that you will get raped in this degree at my University.

>>100814568 To elaborate, failed means failed the exam and has to retake it. You get 3 chances of doing a written exam (with am mark between 1.0 and 4.0 best->worst) and after that you can do an oral exam which is either 4.0 or fail. If you fail THAT you completely fail the course and can't take it ever again in Germany, which means you most likely will be expelled unless it's an elective or so.

>>100814580 No, an F is failing Failing means you don't get credit for the course By definition a C- and higher is NOT faililng Anybody who tries to argue otherwise should be shot

>>100814909 Except you're wrong and throwing a tantrum wont make you any less wrong.

>>100814787 It's similiar here, I'm this guy: >>100814558 First year "assessement year": 11 exams, you have to pass all. Not passed Exams can be retaken the next year. If you don't pass it then, you're are banned from that degree for 10 years in the whole country. At maximum you are allowed to fail 6 exams. To pass you have to get a 4, worst grade is 1, best grade is 6.

>>100814971 You didn't even explain why I'm wrong Now then, how is anything I said incorrect

>>100815058 Holy christ that's strict. If it were like this over here I'd be expelled long ago. Then again, I'd probably study harder and not post on the internet at nearly 5AM.

>/a/ - Anime & Manga

>>100803747 I was right, Christina, you are perfect. You understand. Let's stand together with hands in our pockets.

>>100814909 >By definition a C- and higher is NOT failing in the eyes of the school. ftfy

>whatever The educational system failed a long time ago in most countries, because of the rising population in the world, the only reason it still exist after they couldn't keep fixing it is filtering, they don't care anymore about if you understand or not they only want the few of the best and getting ride of the rest. El psy congroo

>>100815136 It was really sad for a friend of mine. He passed all exams but one which he failed with a 3.75 (remember, you have to get a 4 to pass). He literally failed because of half a point and lost 2 years of his life for nothing.

>>100814787 Netherlands here, I'm this guy: >>100814656 Exams for courses are usually only given once per year. Then 2~ months later during the next exam period there are resits for the exams of last period. If you fail both you have the opportunity to retake them next year. The main problem of failing is that you'll get delays due to required prerequisites for projects. Most simple courses don't have entry requirements. Exams are graded on a scale from 1 to 10, where a 6 or above means you passed. Most professors just make the scale linearly to questions answered correctly on exams, with variable points available per question.

>>100815289 No, that's technically what a failure is. I can personally believe that I'm god. Does it mean I'm right? No. If you believe that you failed with an A-, congrats. But that's completely wrong, because you passed the class, and can't retake it for credit. Jesus christ

>>100815512 I am in my second year in university and still can't see the point of using credits, anyone mind to explain.

>>100815340 Yep, I'm the guy you quoted. Pretty similar here; I can't take Theoretical Physics 4 since I couldn't finish 3 last week (failed the first try due to a too busy schedule, got ill for second one).

>>100815701 seriously dude? To graduate, you need to amass a certain number of credits. At my school it's 120. Say you're taking 16 credit units in your last semester of school. You have 105 units total. You end up getting an A, B, C and an F. Every course is 4 units, and you get 4 units for every course except the one you failed. Thus, your total units become 105+12=117, which isn't enough to graduate. You would be stuck taking summer courses in order to graduate your school

Great anime thread.

>>100814909 >>100815512 Don't know what crap school you go to, but at any decent university if you get a C- in a class for your major, you don't get credit for it. You may get university credit, but you don't get credit for your major, so you'll have to take it again regardless. Non-major classes are different, those you can scratch by with a D and still get credit, but only to a certain extent.

>>100815798 is your Physics 4 about moment of inertia and inertia matrix and so, if yes i can insure you it's really simple, not that much but with practice it get really simple.
