Homework Help: Maths - Trig

Posted by TP on Thursday, February 19, 2009 at 1:21am.

I just had a test, and one question I tried heaps of times and I still couldn't answer. It was "Prove secèsinè + cosecè cosè = 2cosecè "

Can someone please tell me if proving this is possible at all? (But don't tell me how to solve it)
