Integration by parts twice should do the trick. To start you off:
Apply integration by parts again on the blue. Then you should recognize the new integral
I tried using both sin(5x) and as u and all I ended up doing was coming up with the same problem again, except with a constant pulled out in front. There must be some trick I need to use on this problem that I am not seeing.
Thanks, I never would have thought of that, I just figured I was doing something wrong. But what about the constants out front? In this case I came up with:
So what I add it to the other side, I should get:
Would I then multiply everything on the other side by
To give the correct answer?
