摘要
辅助函数法是处理和解决数学问题的一种重要思想方法。在高等数学解题中,往往不是直接对问题本身进行求解,而是根据问题以及所给的已知条件,巧妙地构造一个适当的辅助函数,从而间接有效的解决问题。
Auxiliary function is an important thinking method in dealing with math problem. In the course of solving advanced mathematics, we are not always direct to the question itself but base on problems and the known factors to construct a proper auxiliary function to solve the problems indirectly.
