Consider the operation D[f[x]g[x],x]=g[x]f'[x]+f[x]g'[x] Does anyone know how to make Mathematica perform the inverse operation. I guess what I am looking for is some kind of Simplify Function using differentiation rules. Something resembling the Factor Function would also be nice. Thanks for any tips Hemming
