hi I have been trying this question for quite a while now and am unsure of what to do. Any help would be apprectiated.

Integral x^13 cos(x^7) dx

I know you have to use integration of parts. Here is what i have done so far:

let U=x^3

dU =13x^12 dx

dV=cos(x^7)

V=?

First off I cant manage to find the antiderivative of cos(x^7)

After finding that i think you use

integral u(dV) = uv - v(dU)
