I want to use the map function (/@) or similar to do that for me automatically. Your help is really appreciated. We may need more information: (1) do you literally want T1[x], T2[y], T3[z]? or are these actual defined functions. If the latter, then there's the difficulty of the way Mathematica reorders expressions automatically -- e.g.: T1[x_]:=x^2 T2[x_]:=Sin[x] T3[x_]:=Exp[x] T1[x] + T2[y] + T3[z] Exp[z] + x^2 + Sin[y] Thus we no longer know which function is which! (2) Does each of T1[x], T2[y], T3[z] depend on _only_ the one indicated variable x, y, z or, to the contrary, does T2[y], say, also involve x and or z? --- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
