摘要
一个函数经过求导运算后会有许多独特的性质,本文主要讨论导函数没有第一类间断点、导函数的介值性等特性,并举例说明运用这些特性解决具体问题.
A function has many unique properties after its differential operation. The article mainly discusses the following two properties of derivative function. One is its lack of the first - kind discontinuity points and the other is its intermediate - value property. It also presents some examples to illustrate how to solve concrete problems by using these special properties.
