1. The problem statement, all variables and given/known data indefinite integral dx/((e^x)(sqrt(1-e(-2x)))) using integration by parts evaluate the integral. 2. Relevant equations integral u*dv = u*v- integral v*du 3. The attempt at a solution To be completely and entirely honest i am not even sure where to start with this problem. I have finished other integration by parts homework questions in this assignment but this one i can't find something to choose for u and dv that will work out correctly.:grumpy: I have been at this problem alone from almost 2 hours. Any help would be greatly appreciated.
