浅谈数列极限的“ε-N”定义的教学

Something about the Teaching of the "ε-N" Definition in the Limit of an Ordered Series of Numbers

通过数列极限的直观描述和“语意”上的过渡,得出数列极限的“ε-N”定义,并阐述如何应用数列的“ε-N”定义来证明数列极限的方法与技巧。

This paper presents the 'ε-N' definition in the limit of an ordered series of numbers through its object description and meaning transition,and sets forth the methods and techniques of proving the limit of an ordered series of numbers by using the 'ε-N' definition of an ordered series of numbers.
