    Post Verifying Trigonometric Identities

    Good day Math Help Forum Team!

    I am quite confused about verifying identities, especially on complex numbers. I have insufficient examples on my book, therefore confusion is the result. I go several expressions which I think will help me, but I can't solve it.

    1. 1/Tanx+Cotx = SinxCosx
    2. Cosx/1+Sinx + Cosx/1-Sinx = 2Sec
    3. Secx+1/Tanx = Tanx/Secx-1
    4. Tan^2x/Sec^x + Sinx/1-Cosx = Cotx + Secx + Cscx
    5. Tan^3x + SinxSecx-SinxCosx/Secx-cosx = TanxSecx+Sinx

    Thank you very much Math Help Forum! More power!

    Please don't post more than two questions in a thread. Otherwise the thread can get convoluted and difficult to follow. See rule #8: http://www.mathhelpforum.com/math-he...ng-151418.html.

    Also, please show what you have tried and say where you get stuck.
