    Evaluating Inverses of the Trigonometric Functions?

    tan(tan^-1 6/11) how exactly do i evaluate this? I've got no idea how I'm supposed to start with this or anything? Or what about the same thing with sine instead of tan?

    The tangent and inverse tangent functions are inverses, which means they "cancel each other out".
