I'm a little rusty when it comes to these kind of integrals. Any help would be appreciated.
Find the indefinite integral of [(x^2 + y^2 - 2y^2)/(x^2 + y^2)^2]dx, that is, integrate with respect to x. I understand that I need to treat y as a constant, it's the integral itself that I'm having trouble with. Sorry if that's difficult to read, I still need to learn latex.
I will start you off (remember, we are treating y as a constant throughout the entire problem)
We employ the method of partial fractions:
...i think you know how to solve this, let's get to the meat of the matter
now just find the integrals on the right: factor out the on the bottom of the first so you will get it in the form to use arctan, for the second, use trig substitution,
