最值问题一直是高中数学学习的重点内容之一,也是历年高考考查的内容之一.纵观高中教材我们不难发现,求最值的方法概括起来主要就是代数法和几何法.线性规划中最值问题的几何解法就是一种典型例子,很多看似和几何无关的最值问题用类似的方法来做,你会发现不仅计算量小而且思维更优化. The most value problem has always been one of the key contents of high school mathematics learning, and also one of the contents of college entrance examination in the past years.We can easily find that the most valuable method is the algebraic method and the geometric method. The geometric solution to the most problematic problem is a classic example. Many of the most valued problems that seem to be unrelated to geometry are done in a similar way, and you find that they are not only computationally intensive but also more thoughtful.
