Are you certain you've not previously defined one or more of the variables before attempting the InverseTransform? I have no difficulty with eitehr Exp[-t] or Exp[-t^2] here. That is: In[1]:= InverseFourierTransform[Exp[-t], t, w] Out[1]= Sqrt[2*Pi]*DiracDelta[w - I] In[2]:= InverseFourierTransform[Exp[-t^2], t, w] Out[2]= 1/(E^(w^2/4)*Sqrt[2]) In[3]:= $Version Out[3]= 5.2 for Mac OS X (June 20, 2005) -- To reply via email subtract one hundred and four
