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] + 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?
