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$\pi$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.
