sin(10x) and cosx are not multiples of derivatives of each other, and it doesn't seem like you can manipulate powers here.
Looks like you need to use products to sums.

What is RCR
Reverse chain rule

Thats not RCR tho - you have to use product to sums then just integrate the vanilla trig functions you get out of it
