Hi there Is there a Mathematica function which one can use to identify another given function within an equation. I would like to do, for instance, the following: F[x] = ...function..... (this is given) DF[x] = D[F[x],x] (derivative of F] I now want to simplify DF[x] and identify the original function F therein and then let Mathematica write out DF as a function of F instead of using the defined F. Can this be done Thanks for the help Antonie Kotze aak at rmbmain.rmb.co.za
