最值问题一直是高考的热点,也是难点.一元最值问题主要以函数知识为命题背景,借助导数等函数相关知识进行解题;二元最值问题常以不等式相关知识为命题背景,借助常用不等式解题,也可利用换元思想解题;三元最值是一类背景知识丰富的问题,所以其解法也灵活多样、既有体现数学技巧的,也有通性通法的.此类问题对于学生是个难点,本文借由两道高考题,展开对三元最值问题解题策略的 The most value problem has always been the college entrance examination hotspots, but also difficult.Unified one value problem mainly to functional knowledge as the proposition background, with the help of derivatives and other functions related knowledge to solve problems; binary most often problems often inequality-related knowledge as the proposition background, Inequality problem solving can also be used to change the yuan to solve the problem; ternary value is a class of background knowledge-rich problem, so its solution is also flexible, both to reflect the mathematical skills, but also through the general method. For students is a difficult point, this article by two college entrance examination questions, start the problem of solving the most ternary strategy
