 Author Comment/Response Sumit 11/24/12 00:59am HI, Giovanni, Let me start from the second one. I think the solution is to define a variable, not a function. Like g[x_, y_] := x^2 + y^2 f := g[x, y] Now you can use either g[x,y] or f as you wish Plot3D[Exp[-g[x, y]], {x, -1, 1}, {y, -1, 1}] Plot3D[Exp[-f], {x, -1, 1}, {y, -1, 1}] will give same thing. Now I am not sure about the first part.If you want it only for output purpose you can use StringReplace. For example StringReplace["Sin[f[x]]+f[x]^2", "f[x]" -> "f"] gives "Sin[f]+f^2" Hope it will help. Best -Sumit URL: ,
