摘要
为了灵活应用Lagrange中值定理求极限,证明不等式以及确定代数方程根的存在性等问题,探讨了根据Lagrange中值定理的特点,并结合给出问题的已知条件和结论,灵活地分析解决上述问题的方法,并给出了实例分析.
This paper discusses the problem of how to use Lagrange mean value theorem flexibly to solve limit,to prove inequation and to identify the existence of root of algebraic equation.It also discusses the methods to analyze the given problem in terms of characteristic of Lagrange mean value theorem and the given condition and conclusion of the given problem.In addition,some real examples are put forward.
