1. The problem statement, all variables and given/known data Is there a simple way to evaluate S x^5 / [rt(x^2-ax)] dx ? That is, the indefinite integral of (x^5) / [square root of (x^2-ax)]. 3. The attempt at a solution My idea was to rewrite it as x^(9/2) / [rt(x-a)] and then do the substitution u = rt(x-a). Then you get S 2(u^2+a)^(9/2) du But this too is difficult to evaluate.
