I'm failing my calculus III class bros

Just reading calculus it gives me anxiety. The problem is not the subject but the fucking exam with no time to do everything

>studying STEM
your own fault
t. humanities brainlet

But I want good job. Only other option is healthcare

Multivariate calculus is easy

These were the """easy""" problems. God I hate being a brainlet

Did you find the solution? I'm curious, it's been a while since i've studied calculus. Do you need to use the jacobian matrix or something like that?

easy, mate.
convert to polar coordinates, integrate over radius and angle and divide result by 5

Those are easy tbf, you just need to integrate in function of x considering y as a constant and then in funtion of y (and vice-versa for item b).

this is basic shit, mate, literally just integrate the stuff; you can switch order of integration because of fubini's theorem, I think

not being rude btu that is not hard
Taking a as an example:
dx is on the left so you differentiate with respect to x first and then put in 2 and 0 for both x terms
then do it again in terms of y and put in 1 and -1.

We did this in Year 2 Engineering Maths class.
It's really not bad lad.
If you know integration it's just doing the same rules over again except twice.
COME ON.
