    Verify each identity:
    8csc^2 x-3cot^2 x=3+5csc^2 x

    X= theta
    Spaces only to separate exponent and x

    Only 3 steps

    Do you want me to do all of your work for you on all 6 of your posts? What have you done to verify these identities?

    I am studying for a test and didn't get these questions on my study guide. A brief step by step explanation would be quite helpful...

    We all can help, but if you have a test, you should know how to approach a problem. Get it started and someone will come along to help.

    I honestly do not know how to approach this problem. It looks so crazy. I did some of the other ones though to start...

    As with all such identity proofs, first convert the csc and cot functions to their sine and cosine equaivalents, then simplify the resulting equation. It comes right out as long as you recognize that sin^2x + cos^2x = 1.
