拉格朗日中值定理的一些用法

Some Applications of Lagrangian Middle-value Theorem

通过实例说明了利用拉格朗日中值定理求极限和证明不等式,克服了用常规方法求极限、证明不等式的局限性,且相对简便.

Through some examples, these are showed that, the limit is extracted and the inequation is proved using Lagrangian middle value theorem ,and it solves the limitation of the general methods to work out limit and to prove inequation, and it also makes all of these easier.
