SUMMARY

The discussion centers on solving Fourier transforms, specifically the Fourier transform of the function f(t) = exp(-|t|), which is calculated as \(\sqrt{\frac{2}{\pi}} \cdot \frac{1}{1+\omega^2}\). The user faced challenges with the inverse Fourier transform involving an odd function (exp(iωt)) multiplied by the even function derived earlier. The resolution involved recognizing that the inverse Fourier transform of an even function simplifies the process, leading to a successful conclusion.

[SOLVED] Fourier transforms

Homework Statement


Please take a look at the following:

http://books.google.dk/books?id=9p6...M_p7C1N&sig=M8eywUTmbsWbFY6OCqSth13LWFE&hl=da

I have shown that the Fourier transform of f(t) = exp(-|t|) = \sqrt{\frac{2}{pi}}\cdot \frac{1}{1+\omega ^2}.

Now I am having trouble with question A. I know what the inverse Fourier transform is given by, but the we have an odd function (exp(iwt)) multiplied to an even function (the above). This results in an odd function, so how do I rewrite it?

Ok, I read something about the inverse Fourier transform of an even function, and it adds up now. Problem solved.
