How rigorous must the proof be?

What theorems can be used? - December 27th 2010, 03:21 AMHallsofIvy
An "epsilon-delta" proof would be long and tedious. A proof using the facts that , , and are continous functions and that the composition of continuous functions is continuous would be almost trivial.
