Formal definition of limit at infinity

WebIn such cases, it is often said that the limit exists and the value is infinity (or negative infinity). However, some resources say that the limit does not exist in this instance, simply because this restriction makes other theorems in … WebAboutTranscript. The epsilon-delta definition of limits says that the limit of f (x) at x=c is L if for any ε>0 there's a δ>0 such that if the distance of x from c is less than δ, then the distance of f (x) from L is less than ε. This is a formulation of the intuitive notion that we can get as close as we want to L. Created by Sal Khan.
