I got my comfy hybrid course with lovely video lectures from a lad with a soft Texan accent.
feels good man
though the 2 hour/week in-class meetings are totally nerve wrecking because all the lectures are online and everything else is group work/activities I'm too retarded to do on the spot
Isaac Martinez
you must be a sophomore. has your advisor told you what you're taking for the next two years?
Jack Adams
lol just lol
Jack Sanders
I remember my first optimization problem
Kayden Adams
That doesn't sound like undergrad real analysis, OP. Unless he was just testing that you can perform a proof I think you should bail out and take a real real analysis class with someone else. This guy is probably going to skim over the fundamentals and try to teach you material that you'll go over in real analysts II.
Nicholas Robinson
>Using the card and pen I provided you, prove Gauss' Divergence Theorem
He doesn't say what results you can use in the proof, so just write it is a trivial result of the generalized Stokes' theorem.
Charles Scott

Andrew Torres
Or OP made it up, not knowing what real analysis is about.
Cameron Adams
fucking ridiculous how does he gets to understanding part or not something which goes well with him. That's a bummer.
Landon Brooks
Did OP say he was in undergrad? This exercise is perfectly doable for someone with enough mathematical intuition to make it in a career where real analysis is needed.
Austin King
Yuropoor here, someone fucking explain to me the difference between Calc I, II and III and Real Analysis I, II and whatever else.
Jason Williams
you didnt take out phone and google it to btfo the professor when he came back?

Daniel Lopez
calc 1: derivatives and some maximization/minimization problems and riemann sums
calc2: integrals and i don't remember
calc3: more integrals related to 3d shapes and i don't remember
calc4 or multivariable calculus: mega integrals and danker 3d shapes and more methods to calculate wild shapes using integrals
intro to proofs and mathematical induction: self-explanatory
real analysis: proofs behind calculus and random shit
Christopher Roberts
In Europe we have calculus in prep school/gymnasium/high school, this is what they call Calc I in America. Calc II is multi-variable calculus and vector calculus. Calc III is differential equations course.
> real analysis: proofs behind calculus and random shit
So you're telling me they don't teach Calc with proofs?
What is this? When do they take 300's courses? A lot of this stuff we did in the first year.
I don't get it. I'm not getting anything. From what I see, there's nothing special, so why the fuck does everyone say US unis are so much fucking better? What the fuck is happening here? Is WSU just shit, or is it like this everywhere?
Luke Young
pure kek
Jack Walker
>So you're telling me they don't teach Calc with proofs?
Only in honors calc
Cameron Richardson
In Europe we always get taught proofs. We had calculus proofs in high school.
Levi Wright
No you didn't. You're probably confusing them with laid-out theorems and facts to help solve those problems.
Ryder Campbell
Lol even here in Mexico we do that. >mfw amerifats don't take topology until grad school
Ayden Martinez
>stocce fucking kek
Justin Clark
Listen, having an algebraic manipulation of a formula (such as the power rule for differentiation) is not the same thing as analysis.
Nolan Jenkins
In HS I did "proofs" ans did saw some set theory and logic and methods of proofs in general. Yea, it was still mostly plug and chug and algebraic manipulation, but we derived shit. In uni I started by constructing the reals first in the synthetic approach and then with cauchy sequences. We had the formal definition of a limit some basic shit about accumulation points and continuity/uniform continuity. We then went on to define the derivative and (with the definition of the limit) prove all the most important results and then went into application. That was calc 1. Calc 2 we motivated and constructed riemann sums and proved all the properties of integrals from that construction, then we proved the FTC and went on applications. In calc 3 we generalize everything, but we motivate many basics notions of topology and proved basically everything. Calc 4 the same with calc 2 but the professor had to admit that certain proofs were not in the range of the course because it dealt with measure theory but we proved whatever we could.

Americans are so fucking retarded. They don't even have first order differential equations in high school.
Leo Ramirez
Applied math student here. We have to know how to prove theorems too. At least here, in Russia.
Chase Watson
And yet Americans are the only ones to set foot on the moon and we are the ones creating every single major technology that everyone in the world uses.

You think that would have happened if we didn't import all the best german and japanese scientists after the war?

>They don't even have first order differential equations in high school.
literally kek, I didn't know schools in first world could be this inefficent
Leo King
Dude, they did, Europe has higher standards. But only the French got results for some reason.
Jack Brown
Operation Paperclip. Never forget it when talking about how the US got to the Moon.
Christopher Rogers
bull fucking shit you proved fundamental independence or taylor's theorem in your cal 1 class dont even lie to me you stupid snow nigger
Joshua Ward
if you're so smart help me with my OP
Jeremiah Scott
I'd like to believe this is true but I've literally never met a European who wasn't incredibly average intellectually
Samuel Gutierrez
He probably thinks delta epsilon "proofs" of limits are analysis tier.
