## Homework Statement

## The Attempt at a Solution

I'm really at a loss on this question, which is why i have achieved so little on it so far. I think i more or less understand what a fourier transform does (transpose amplitude vs time to amplitude vs frequency, ie the fourier transform of two combined sine waves would be two spikes in frequency space).

In part a) i'm not sure how to express the product of d functions d(x)d(t) as a fourier type integral.

Any help appreciated.
