1. The problem statement, all variables and given/known data evaluate the integral. 2. Relevant equations [itex]\int (cotx)[ln(sinx)] dx[/itex] how would i do this using basic integration techniques from calculus 1? i am not allowed to use, int by parts, partial fractions, trig sub, etc.. 3. The attempt at a solution i tried doing a u=sinx but don't know how to get the cotx.
