摘要
极限概念是微积分学中最重要,最基本的概念。掌握好利用定义证明函数极限是学好高等数学的基础。极限有数列极限,函数极限,多元函数极限等几类,本文直接或间接地用极限定义来证明一些我们经常见到高等数学问题。
The concept of limit is the most important part in the calculus and the most basic concept. It is the foundation for learning well advanced mathematics to master the method of using the definition to proof function limit. Limit includes several kinds, such as, columns limit, function limit, limit of function categories, and so on. In this article, the limit definition is directly or indirectly used to prove the problems we often see in advanced mathematics.
