多元函数极值的判别法则的探讨

Research on the Distinguish Rule about the Extreme Value of the Multiple-value Function

文章讨论了多元函数的极值问题,并将二元函数的极值判定定理加以推广,得到关于多元函数极值的判定法则,并举例说明其应用,这对微积分的教学有一定的指导意义。

With the discussion of extreme value problem of the multiple-valued function, and the popu- larizing of extreme value theory of the two-value function, This paper obtains differentiation rule about the extreme value of the multiple-value function, and illustrates the apllication of the theory with the example, providing proper guidance for the teaching of calculus.
