#14997 — Re: Decoupling E and I

Hello Dave,
Yikes. I don't think this is a good idea, but this will work:

Unprotect[E]
E[x_] := Exp[-x^2]
Plot[E[x]^x, {x, -1, 1}]

(* but note the potential confusion with the following *)

D[Exp[x], x] // StandardForm
D[Exp[x], x] // InputForm
D[Exp[x], x] // TraditionalForm



It is suggested practice to use a lower case letter as a first letter for own symbols, e.g.
pecletNumber = 2
