In Version 4 Mathematica was smart enough to know that FourierTransform[f'[x], x, k] should give -\[ImaginaryI] k FourierTransform[f[x], x, k]. Version 5 seems no longer to do this -- a nice classroom demonstration and a valuable method of solving differential equations down in flames. Why is this? Tony Harker (Dr A.H.
