Hi Andrzej, Thx for your help, I think I understood where my error was. To elaborate on this part: > I am not sure what sort of "readability" problem you > are referring to? > You could of course use: > > f3[x_, p_] := Evaluate[f[x] /. params] > > but I am not sure whether this helps? As I explained in the reply to David, the problem is that my example was just a very simplified example of my real function, which depend on several variables and parameters, with some parameters dependent on another parameter. This function I have then to inject in another function, which I want to derivate which... I noticed that all this quickly gets a nightmare, I thus wondered about a method to keep every step the clearest possible. Your evaluate looks interesting, but I just found out that I can use params[p_] instead of params. Thanks, Johannes
