    1. The problem statement, all variables and given/known data
    Tan^3Theta


    2. Relevant equations

    Tan^2Theta=1-cos2Theta/1+cosTheta

    3. The attempt at a solution

    What are you trying to reduce it to?

    until there are no terms with a power greater than 1

    Then you can just replace tan by sin/cos in your third line and multiply out and you will have no term whose power is greater than one.
