Tricky Trig Simplification, or so I think

  1. Feb 20, 2012 #1
    1. The problem statement, all variables and given/known data

    Simplify:

    sin^3(x) - tan^2(x) - cot^2(x) - cos^2(x) + 1 - sin(x)

    2. Relevant equations

    n/a

    3. The attempt at a solution

    I don't know where to go after I get to:

    sin(x)[sin(x) - cos^2(x)] - tan^2(x) - cot^2(x)

    I think it might help to replace cos^2 with (1 - sin^2), and it might help to replace cot with cos/sin and tan with sin/cos
