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) = $$\int$$(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.
