关于微积分里多元函数极值问题的研究

Studies on extreme value of multivariate function in the calculus

多元函数极值是微积分课程的一个重要概念 ,文章通过定义并结合具体实例将极值和弱极值概念作一对比 ,以说明它们的区别。

The extreme value of multivariate function is an important concept in the calculus. In this paper, the differences between the extreme value and weak extreme value in concept and in use are discussed. Meanwhile, the differences between the conditional extremum and unconditional extremum in concept and evaluation were also discussed.
