再谈条件极值的初等解法

A Discussion on the Elementary Solution of Conditional Extreme Value

阐述了利用几何平均值、柯西不等式排序原理及光学原理是解决条件极值的初等解法的有效方法 .

This article elaborates that it is the effective way for the primary solution of conditional extreme value to use methods of geometrical mean,Cauchy inequality,collating principal and optics principles.
