Hi MathGroup, The input Integrate[ f'[x] g[x] + f[x] g'[x],x] gives f[x] g[x]. I think by a rule associated with Integrate. But Integrate[f'[x] g[x],x] + Integrate[f[x] g'[x],x] also produces f[x] g[x]. This is quite nice, but I do not understand how this happens by looking at the standard Mma evaluation procedure. Is there a hidden rule for Integrate over Plus? Thanks for an answer, Michael Trott trott at physik.tu-ilmenau.de
