摘要
以多元函数条件极值为例,分别用拉格朗日乘数法、无条件极值、初等方法、几何方法解题.不仅融合了多方面的数学知识,又体现了应用意识.
Taking the conditional extreme of multivariate function as an example,this paper uses method of Lagrange multipliers,unconditional extreme,elementary method,and geometric method to solve the problem.It not only integrates many aspects of mathematical knowledge,but also shows the application consciousness.
