1. The problem statement, all variables and given/known data Represent f(x) = sinx if 0 < x < pi = 0 if x > pi as an integral 3. The attempt at a solution I first try to find A(w) = [tex]\int[/tex](1/pi)sinv cos wv dv between 0 and pi. How on earth do I solve that integral? I've tried to use the product-to-sum formula, but the values of the integral depends on the value of w.
