【摘要】 数学分析作为经典数学的重要基础知识的一个分支 ,其思想、内容和方法的内涵极为丰富。对初学者来说 ,做习题是很困难的事 ,但有些习惯的解法是有规律可循的。其中构造函数法就是常用的一个方法 ,例如拉格朗日中值定理和柯西中值定理等许多定理和命题都是用构造函数法来证明的更多还原

【Abstract】 Mathematics Analytic is branch of important basic knowledge for classical mathematics.The intention is so rich for the idea,content and method.For beginning man,Solving problem is very diffcult thing.In fact,it is regular to find right answer for the exercises.Usually,people apply the method of structural function.For example,Lagrange mid-valve theorem and Cauchy mid-valve proposition was proved by the method of structural function.更多还原
