摘要
介绍了用多项式根的性质与导数极限定理求分段函数在分界点的导数的简单方法。
The paper introduces the property theorem about roots of polynomial and the derivate limit theorem,by which we can study the derived number of a break point of piecewise function.This paper expanded the method of studying the derived number of the break point of piecewise function.\;
