    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 x = y \tan \theta

    can you take it from there?
