关于一元函数可微条件讨论

The Research on the Differentiability Conditions of Univariate Function

本文通过两道例题讨论了当一个特殊极限存在时,一元函数在一点处可微的情况.给出一元函数在一点处可微的一个特殊结论及证明,并计算出导数.

In this paper, the differentiable of function of one variable is discussed through two examples, when a special limit existed. Elicited a special result of differentiable of univariate function at a point and proved it, calculated the derivative.
