Another example (you don't need to solve it for me) is

Integral (xsinx)/((cosx)^3)

I realize I have to change it, and I do change it to xtanx(secx)^2, but the x out in front gives me trouble. My point is this. When you look at a problem and see that you have to fiddle with it, is there a list of generalized steps that you follow to try and make it look like a solvable equation? The previous integral I posted just needed some algebra steps to make it solvable, so I'm starting to think I'm behind on algebra.
