摘要
基于构造辅助函数在高等数学解题中的重要性,针对微分中值命题中值存在与方程根存在的问题,提出三种构造函数的方法:常数变易法、直接构造法、联想公式或定理构造法,并结合实例说明构造函数在解题过程中的重要作用。
Based on the importance of constructing auxiliary function in advanced mathematics, aiming at the problems in the existence of the differential mean-value proposition, and of the equation root, three construction methods of function are put forward： constant variation method, direct construction method and associating formula or theorem construction method, and combined with examples the important role of construction function in problem-solving process is explained.
