I tried to compute the Fourier Transformation of
standard Guassian distribution (exp(-x^2/2), or say I
typed:
Integration[Exp[-x^2/2]Cos[kx],{x,-Infinity,
Infinity},k->Constant]
The result was:
Sqrt(2*Pi)cos(kx)
which was obviously wrong and the correct answer
should be Sqrt(2*Pi)exp(-k^2/2).
I changed another way to define k
(SetAttributes[k,Constant]), the result was still the
same ridiculous. Can anyone tell me why?
Many thanks.
