    Proving A Trigonometric Identity
    Usually I am pretty good at these, but this one is killing me. Please help!

    Never mind I solved it. Here's the answer if anyone is curious.

    it's 5am here... so I may be a bit off. I'll get you started:

    tan = sin/cos
    cot = cos/sin

    numerator: sin^2 - sin/cos
    denominator: cos^2 - cos/sin

    take out sin from num, cos from den

    you end up with

    sin(sin - 1/cos)
    ==========
    cos(cos - 1/sin)


    so you can get 1 TAN out of that. Hope that gets you started.
