    Trig Identities - Proof

    How would I add this?

    2+(sin^2x/cos^2x)?

    I'm not good with fractions.

    why use fractions at all ?

    2 + \frac{\sin^2{x}}{\cos^2{x}} = 2 + \tan^2{x} = 1 + \sec^2{x}

    the original equation is ((2+ tan^2x)/(sec^2x)) -1

    that is not an equation ... what is it equal to ?

    in future, please post the entire problem from the start ... as it is, I have no idea what you are trying to do.
