摘要
针对分段函数在分段点的可导性问题,使用理论证明以及反例证明等方法,得出三种典型分段函数在分段点可导的条件,举例说明结论的应用推广价值。
As for the derivative of piecewise function at dividing point,this paper gets the conditions of three typical piecewise functions at dividing point by using relative theory and counter-example;and it illustrates the application promotion value of the conclusions with some examples.
