隐函数取极值的充要条件及其应用

The necessary and sufficient condition of the extreme value of implicit function and it's application

将显函数取极值的必要条件和充分条件加以推广得到隐函数取极值的必要条件和充分条件,从而使隐函数极值的求解变得更为简捷.

By function, we can function, so as to generalizing the necessary and sufficient condition of obtaining the extreme value of explicit acquire the necessary and sufficient condition of obtaining the extreme value of implicit make the solution process simpler and more convenient.
