摘要
本文举例说明了一元函数的导函数的极限与函数的可导性的关系,证明了一元函数的导函数在某点的连续性的命题,并列举了两个应用该命题的例子。
This paper illustrates the relation between the limit of derivative function and derivability of the function for functions of one variable by examples.The author proves a proposition which is about continuity of derivative function at a certain point for functions of one variable,and illustrates applica- tion of this proposition by two examples.
