Help with Integration
I have a horrible integration which I have whittled down to a few easily integrable terms, but one of them is giving me pain, can anyone here help?

here it is:

(cos(A)sin(B)sin(2B))/(sin(A+B)cos(A+B))

Re: Help with Integration
just to clarify, I am looking to simplify that equation. A is also a function of B.

Re: Help with Integration
sin(x + y) = sin x cos y + cos x sin y

cos(x + y) = cos x cosy + sin x sin y

is the only non-trivial one i used.

does A = Pi/2 - B

by any chance? that sure would be nice.

Re: Help with Integration
Why not just use maple/mathematica like everyone else who wants to integrate things outside of a tedious methods class?
