Integration by Parts HELP!

Hey, I am working on some calculus and I am having some trouble with the last few integration by parts problems. I got the first couple, and i grasp the concept of integration by parts but for some reason I just can't figure these 3. Any help would be greatly appreciated.

1. The integral of (e^2x)sin3xdx

2. The integral of cos(3x+1)cos(5x+6)dx

3. The integral of x²ln²xdx

P.S> Feel free to ask if you can't read the questions, I tried to write them out the best I could.


Thanks in advance,

Brian
