摘要
本文是在费尔马定理的基础上,得出了一个推论,由这个推论再引入辅助函数,然后比较容易地证明了四个微分中值定理,
On the basis of the Fermat's theorem, a new theorem is established, by which the auxiliary function is introduced. Then four differential mean value theorems are proved without difficulty. And the advantage here is that the auxiliary function is readily initiated and the proof is easy to understand as well as natural.
