Thread: Need help integrating

Hey all, I just have an interval that needs anti-deriving. Here it is:

integral of x^2/(x^2+y^2)^3/2 dx

Thanks for any help you can provide,
Dave

remember, we are integrating with respect to x, thus we treat y as a constant here. how would you do it if y was just some other number? the conventional way would be to use a trig substitution.

let

can you take it from there?

Thank you sir, I think I've got it now.
