Limit of a function of a real variable
Definition.A function f (x) is said to approach a limit l as x approaches the value a if,given any small quantity ε ,it is possible to find a positive number δ such that f (x) l < ε for all x satisfying x a < δ .这个定理叫什么名字,中文版本是什么?英文好难理解啊

就是极限理论的 ε,δ 语言 其中文定义如下:函数极限的专业定义:设函数f(x)在点x.的某一去心邻域内有定义,如果存在常数A,对于任意给定的正数ε(无论它多么小),总存在正数δ ,使得当x满足不等式0
