I am totally baffled by the following Mathematica behavior: In[1]:= InverseFourierTransform[FourierTransform[x^2, x, y], y, x] Out[1]= Sqrt[2 Pi] x^2 FourierTransform[DiracDelta[y], y, x] In[2]:= Sqrt[2 Pi] x^2 FourierTransform[DiracDelta[y], y, x] Out[2]= x^2 I've already asked my local guru without success, so I'm hoping someone here can help me. Does anyone know why the first expression doesn't evaluate to x^2 all by itself? How I can force it to do so? Carl
