摘要
本文首先介绍函数乘积和商的求导公式的特点,其次详细探讨基于乘积和商求导公式的解题方法——还原法,以及它们在求解微分方程和中值定理构造辅助函数等方面的应用。
This article first introduces the characteristics of the derivative formulas for the product and quotient of functions,and then introduces in detail the solution method based on the derivation formulas of product and quotient:restoration method,as well as their applications in solving differential equations and constructing auxiliary functions in the mean-value theorem.
