高职高专高等数学中求极限运算所适用的常用方法

The commonly used method of limit operation in higher vocational colleges higher mathematics

高等数学教学中极限的求取是一种重要的、基本的运算方法,但对于高职高专的学生而言,由于知识结构方面相对比较薄弱,数学学习基础不牢固,对于抽象概念的理解与熟练应用也存在一定难度,因而探讨常用的运算方法并总结规律,对于有效教学和提高学习理解程度具有重要意义。

The limit calculationis one of the important,basic arithmetic method in the teaching of higher mathematics,but for higher vocational college students,as the knowledge structure is relatively weak,the learning foundation of mathematics is not firm,the understanding and skilled application of abstract concepts also has certain difficulty,so to investigate the common calculation methods and summarize the law,has an important significance for the effective teaching and improving understanding ability.
