Homework Help: Fourier transform of the sine function?

  1. Sep 16, 2011 #1
    1. The problem statement, all variables and given/known data
    I'm trying to get started on a project for a course, which is about Fourier transforms.
    So I'm trying to find the Fourier transform of sin(2[itex]\pi[/itex]f0t) in order to figure something out.

    I don't really understand the delta function though.

    sin(2πf0t) has only a single frequency, so in the frequency domain, it is a delta function.
