一类分段函数在分段点处的可导性及连续性

The differentiability and continity of a class of piecewise functions at piecewise point

通过应用Taylor公式及导数极限定理,对一类分段函数在分段点处的可导性及连续性展开探讨,并进行推广,得到较好的结果.

The paper discusses differentiability and continity of a class of piecewise functions at piecewise point the continuity and the continuity of a class of piecewise function at the point of subsection by the application of the Taylor formula and the derivative limit theorem, and carries on the promotion, and gets better results.
