摘要
二元函数的极值问题是微积分的典型问题,本文用代数和几何两种方法证明了函数存在极值的充分条件,从而揭示了微积分、代数、几何这三门学科在这一问题上的内在联系.
The extreme value of F(x,y) is a typical problem in calculus. In this paper,we proved the sufficient condition of this problem by algebra and geometry respect.Fathomer,revealed the inner relation among calculus culgebra and geometry on this problem.
