    Unable to simplify an expression

    Hi,

    Very VERY happy to have found this forum, I have a test tomorrow and I'm really stuck.

    I want to simplify the following expression:-



    I really have no clue how to do this.

    If anyone could explain the procedure to me, I will be forever in their debt.

    Many thanks!

    1 - \cos^2 \theta = \sin^2 \theta and 1 - \sin^2 \theta = \cos^2 \theta. these are identities you must know!

    and what is \frac {\sin^2 \theta}{\cos^2 \theta} ?

    Muhuhahahhaaha! you are forever indebted to me! your soul is mine!

    Thank you Jhevon

    I'm lost by this TBH.

    I have to find one more question/area to learn to get a pass mark on my test. Going to work on that and I'll make a thread on it later after a bit more study.

    again, thanks!

    so what's the answer? what is \frac {\sin^2 \theta}{\cos^2 \theta} ?
