int[(x^2 + a^2)^n] dx =
[x(x^2 + a^2)/(2n + 1)] + [(2na^2)/(2n + 1)]*int[(x^2 + a^2)^(n-1)] dx
Where n =/= -(1/2)
I've done a few other examples of integration by parts just fine, but I can't seem to find selections for u and dv which allow me to solve this.
If anyone can grant me the FIRST step, I'm sure I can take it from there.
Cheers!
