1. The problem statement, all variables and given/known data Sec^2x X cotx --------------------- csc x Also, if anyone wants to explain cofunction identities and how to use them, to be that would be very much appreciated. 2. Relevant equations The Pythagorean identities as well as the basic identities of trig functions. Any knowledge of cofunctions. 3. The attempt at a solution I made sec^2x into 1 + tan^2x with one of the identities and broke down tan^2x into tanx X tanx. I also assumed cot could not be broken down into anything but 1/ tanx, which is 1/ (sin/cos). But nothing canceled so I ended up back at the starting line.
