Homework Help: Trigonometric Transformation

  1. Feb 13, 2008 #1
    [SOLVED] Trigonometric Transformation

    This is a calculus 3 problem, but this part involves only trig identities:
    Make the function f(x,t) = sin(t)*sin(x) into the form: f(x+t)+g(x-t).
    I'm not sure whether to use half angle formulas, or what?
