SUMMARY

The discussion focuses on integrating the function f(x) = sin(x) for the interval 0 < x < π and determining A(w) using the product-to-sum formula. The integral A(w) is defined as A(w) = (1/π) ∫ sin(v) cos(wv) dv from 0 to π. Participants express challenges in solving this integral due to its dependence on the variable w and the overlap in the function's definition.

Homework Statement



Represent

f(x)
= sinx if 0 < x < pi
= 0 if x > pi

as an integral

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.
