摘要
数列极限的"ε-N"定义是高等数学教学的起点也是难点,本文就概念的直观定义、抽象化处理等方面阐述了具体教学实践中的一些经验方法。
The"ε-N"definition of limits of sequences is a beginning and difficult section of the advanced mathematics.In this paper,we formulate some suggestions on how to deal with the direct meaning and its abstraction and so forth,by recollecting the experience in practical teaching.
