I haven't had differential equations yet, so I am struggling in your math methods class. I understand what a Fourier Transform is, but I'm having trouble with this particular problem.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Here's a screenshot. Better than I can write it.

3. The attempt at a solution

Here's what I did:

The capital letters have already been transformed, so if I take the inverse transformation, I should end up with what I had to begin with.

Where I get stuck is with the [itex]Q, \frac{1}{D}, \frac{1}{(w^{2}+k^{2})}[/itex]. Is it possible to split the [itex]\Delta[w][/itex] up from the fraction, because that would just be back to [itex]\delta[x][/itex].

If I'm completely wrong and beyond hope, just tell me and I will go cry in a corner.

Thanks!
