Lagrange中值定理辅助函数的构造方法

The Formational Methods of Additional Function in the Value Principle ofLagrange

在证明Lagrange定理的时候,辅助函数的构造往往令大多数学生困惑不解,在参考大量资料的基础上,归纳了5种辅助函数的构造方法.

In the confirmation of Lagrange principle, the formation of additional function is very puzzling to most students. In reference to many materials, this paper puts forward five methods to form additional function.
