So the coefficient in the Taylor expansion is such, that when you naively put 0 for your expansion variable \omega_E, you get 0/0? Yes, in that case you can try the "limit" command in SymPy. Let me know if it can do your expression. Ondrej -- You received this message because you are subscribed to the Google Groups "sympy" group.
