Chain rule, brah

Not sure that works for integrals. I would try substitution.

This should really be in the Math/Science help thread. But for now, the integral of U*dV/dX = UV*(integral)V*dU/dX dX

God that looks ugly. But yeah, both of those are products, so just set one equal to U and one equal to dV/dX and you should be on your way. Looks like you'll ave to use substitution too.

Also, check you answers on wolfram alpha. It's a godsend.
