Trying to integrate (arcsin(x))^2/(sqrt 1-x^2)

So far i have made

arcsin x = u and

du=1/(sqrt1-x^2).dx

I am at u^2 * du

I have spent hours on this and it appears obvious but i just don't get it! sorry

Any pointers i would be extremely grateful. I feel its something to do with the calculus relationship between the values of arcsin and du.

Thanks in advance
