分段函数的导数与不定积分

The Differential Coefficient and Indefinite Integral of Piecewise Function

我们将研究分段函数在分界点的可导性、导数的求法、分段函数原函数存在性问题,并给出分段函数求不定积分的方法.

The purpose of this paper is to study the differentiability of piecewise function at the point of division, and the existence of primitive function, derive the indefinite integration of piecewise function.
