Simplification Through Fundemental Identities

  1. Feb 3, 2010 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    1 +cot2=csc2
    Are these sufficient?

    3. The attempt at a solution
    Confusion. Epic confusion. I might have had it yesterday, but the mathematical equivalent of a writers anti-tank roadblock. At best.

    Ahhhhhhh, thanks...

    a^3+b^3=(a+b)*(b^2-ab+a^2). It's a general algebraic identity. Word to the wise.
