I'm running Mathematica 4 on Windows and found the following odd situation, in: FourierTransform[y'[x] + y[x], x, w] out:FourierTransform[y'[x] + y[x], x, w] FourierTransform didn't distribute over addition. even though in: FourierTransform[y'[x] , x, w] out:-\[ImaginaryI] w FourierTransform[y[x], x, w] worked correctly. I found FourierTransform[u[x]+v[x], x, w] also didn't work even though it did work when expressions were assigned to u and v. BTW: Wolfram support said use Distribute[FourierTransform[...]] as a workaround
