摘要
拉格朗日乘数法是求解条件极值问题的一种有效的方法,也是多元函数微分学部分的重要内容之一。本文利用曲面束探讨了拉格朗日乘数法的几何意义并给出了拉格朗日函数构造的一种几何解释。
Lagrange multiplier is an effective method for solving conditional extremum problems,and it is also one of the important parts of the differential calculus of multivariate functions. In this paper,the geometric meaning of Lagrange multiplier method is discussed by using surface pencil,and a geometric explanation of the construction of Lagrange’s function is given.
