Homework Help: Fourier integral

  1. Sep 29, 2008 #1
    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.

    There is an overlap is the definition of your function.
