关于构造辅助函数证明微分中值定理的进一步探讨

Further discussion about construction of supplementary to demonstrate theory of differential value

微分中值定理是微分学的基本理论 ,其中Lagrange定理和Cauchy定理的证明关键是构造辅助函数 .文中就如何构造辅助函数。

The theory of differential value forms the base of differential calculus,which the demonstration draws highly emphasized attention.The construction of the supplementary function is the key to demonstrating the Lagrange theorem and the Cauchy theorem.The paper discusses such problems further in regards to the single quality and construction of the supplementary function.
