    Real quick simple question...

    Im doing a math problem and I get this far.

    \frac{sin^2Psin^2P}{cos^2P}

    Can that be converted to

    tan^2Psin^2P?

    Thanks!

    \dfrac{\sin(P)}{\cos(P)} = \tan(p)

    \frac{\sin^2(P) \sin^2(P)}{\cos^2(P)} = \dfrac{\sin^2(P)}{\cos^2(P)} \cdot \sin^2(P) = \tan^2(P) \sin^2(P)
