partial derivatives were easy, integrals were hard

>>7371691
So easy I tested out of it.

>>7371696
triple integrals especially, there needs to be more research in this field I don't think its very well understood yet.

>>7371698
is this a meme?

I made a B. Thought the class was pretty easy. I didn't practice the homework enough to earn an A, really. I just wrote matlab scripts to do it for me.

This integration section was cake though. Made a 98 on the first integration exam and a 93 on the second.

well I was struggling with that class cause my dumbfuck teachers never taught me shit and I didn't feel like doing the homework but then one day I was preparing for the final and took a shitload of Adderall and read the entire book in an afternoon, did every exercise in the book and aced the test.

without drugs it's hard, but with drugs I found it very very easy to understand.

Got an A+ in multivariate calculus.
Got an A in vector calculus.
We used Marsden and Tromba.

Easy conceptually. A little more difficult computationally because I didn't put any work into doing practice problems. I think it's one of those subjects where you need to do a lot problems to get comfortable with integration.

>>7371691
Not much. It was the easiest part to study and to do in the exams, both in the Math's and the Physic's exams.

I took the honors level class which was entirely proof based and covered k-forms, the generalized Stoke's theorem, and some differential geometry (Gauss's remarkable theorem). It was pretty hard but rewarding, I got an A+

How about you just admit you're fucking retarded?

>>7371741
same
>>7371812
that sounds badass bro

>>7371812
That sounds awesome. School?

>>7371818
Toppest of keks

>>7371868
Cornell

>>7371872
Fuck. Should have guessed it was somewhere great. Are you finished there?

>>7371818
kek

>>7371875
no, 2 more years.

>>7371818
How about you just admit you need to lurk moar?

took it in high school, didnt really pay attention or do the homework so scraped a b+

none of this shit makes sense, computers were invented for a reason

>>7371995
seriously this
im taking this shit now and we arent in a computer lab.
this shit be so much more interesting with mathematica

differential calculus were harder for me than integral, the only part of integral calculus hard for me was when i had to build the six different orders of integration with triple integrals.
Teacher says, u just need imagination to see them, and it was hard af.
Differential equations were ez too, i liked bcos their applications are amazing.

>>7372023
I wrote matlab scripts for the hw in that class, but one of my friends used Mathematica and it was FUCKING AWESOME. It helps visualize how you're cutting shapes for the triple integrals to reinforce the rules of slicing. Helped me a lot

>>7371730
where i can find adderall bruh?
i want to try so study different, idk if acid works too, ive never tried

>>7372038
You should definitely take acid to study, it'll help tremendously

>>7372038
I've found the stuff helpful in the short term, but incredibly cumbersome with any regular usage. It would take loads of discipline to not take them all the time.

>>7371691
I'm still on single variabel (self-taught)

surface integrals are useful to what I want to do but I can't comprehend it yet

The content is pretty straight forward until you get to vector calculus. That's where shit hits the fan.

The class was a nightmare for me though because the professor was the worst professor I have ever had. She was the biggest goddamn cunt. I had to take a semester break from math before I took diff eq because I was probably going to strangle someone if I had to suffer through another math class right after that hellish experience.

>>7371691
It is easy.

>>7371691

Is that like Calculus III or Differential Equations?

>>7373708
>women teaching math

>>7371691
I study biochemistry so I didn't have to do much multivariable calculus, but it was surprisingly easy to pass the test. I didn't quite understand the theory behind it though, to be honest.

I'm at it right now.

It's ok so far, but Stokes's theorem and Gauss's divergence theorem and application of either is quite difficult for me.
The hardest part for me is knowing when and how to substitute and how to parameterize areas correctly.

>>7373708

What's her ratemyprofessor page?

>>7372023
>this shit be
Maybe you should have taken different classes, retard.

>>7371691
Triple integrals and Stokes' theorem were difficult at the beginning, but when you get the idea it's easy

>>7373950
>when you get the idea it's easy

>>7373950
>Triple integrals and Stokes' theorem were difficult
nice bait

>>7371691
Am I the only one who never had to memorize any of this?

I literally just see that all in my head and I figure out the volume/area elements and shit on the fly

>>7374008
whoa like
whoa

>>7371691
partial differentiation, critical points, inflection, etc were all very easy. almost no thought put in for an A.

the second quarter of it was harder, but very few people took it. (Only the top 10% of the previous quarter bothered to take the second quarter. this happened to be because of some complex scheduling conflict that isn't really relevant to /sci/)

because of the higher quality of the sample the quarter I took it, there ended up being no curve at all. I scored better percentage-wise than previous quarter but ended up with a B instead of an A. Vector Fields and the Vector Analysis Theorems are very easy. Multiple integration and change of basis can get pretty tricky. None of it is very hard in concept, only sometimes in computation.

>>7373717
well, considering that differential equations has only 1 variable and the other a dependent, while calc 3 has multiple variables, why don't you tell us, anon?

>sexism in a field that is almost a 50/50 split

please join us in the current century anon. we've been waiting for you.

I didn't do multi variable calculus.

I did differential geometry and manifolds, Kid.

>>7374548
i do the same thing as that other anon.

its just a sphere or a cylinder there really isn't anything special about this.

Not in department staff or graduates at any decent university.

Women who are interested in maths and good at it are rarer than such men.

>>7371691
Easy and interesting. My second favorite maths course I had to take as a Engineering student.
