## Fourier Tranforms

I was hoping if any1 knows a website that contains exercises and solutions, on fourier transforms or have sample questions to give.... I have only learnt the theory and have know problems to solve ... and I tried Google....
Questions Like:

Determine the Fourier transform of
f(t) = $t/1 + 2t^2 + t4 =t/(1 + t2)^2 .$

Thanks for any assistance
