You're correct. And I don't like the solution. Thanks!

Very Useful indeed. Sep 18 asked Selecting terms from a matrix Sep 16 awarded Nice Question Sep 16 comment Why does Mathematica return a Fourier transform for a function for which it is not defined? sorry I didn't see your 1/Sqrt[2 Pi]. You are right. I don't see how the simplified form is working out though. For example, at $k = 2$ I get $(1+i) / 16 i$ Sep 16 comment Why does Mathematica return a Fourier transform for a function for which it is not defined? Sorry. To follow up on this last comment the difference between your direct approach and the FourierTransform[] result is due to a different definition of the transform. But ... the result only applies to positive k ? Sep 16 comment Why does Mathematica return a Fourier transform for a function for which it is not defined? ok - clever thanks. So as a feature it applies a damping factor. This is a quite close to the FourierTransform[] result but not the same I think. In particular the root 2 has somehow dropped out.

Sep 15 comment Why does Mathematica return a Fourier transform for a function for which it is not defined? is it possible that the generalised fourier transform is being computed? Sep 15 comment Why does Mathematica return a Fourier transform for a function for which it is not defined? Also, I get this result for FourierTransform[x, x, [Omega]]. Surely this can't be a bug?
