Homework Help: Trigonometric Identity

  1. Sep 25, 2006 #1
    Hi, I have a question about a problem:


    I have to find the identity for it and I know that csc is 1/sin and sec is 1/cos but after that I don't see where it can lead to a simple answer. If anyone knows it would be helpful, thanks!
