Trigonometric Identity

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

    1/2csc(THETA)sec(THETA)

    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!

    sin(2x) = 2sin(x)cos(x)

    it should simpify to sin(2x)/4
