In this paper, using different geometric means, the introduction of the corresponding auxiliary function of the Lagrangetheorem proof explored.
本文首先采用不同的几何手段,引进相应的辅助函数,对拉格朗日定理的证明进行了探索。

On the basis of these theories, Rolle mean value theorem, Lagrange mean value theorem and Cauchy mean value theorem are proved by constructing nested interval.
在此基础上通过构造区间套依次证明了罗尔中值定理、拉格朗日中值定理和柯西中值定理。

This paper gives the new method to prove the cauchy mean value theorem which also may be deduced from the Lagrange mean value theorem.
