摘要
拉格朗日乘数法是求条件极值的重要方法,该文通过数形结合给出定理推导的新路径,相比教材上纯代数推导更直观,体现了"几何意义"的重要性.
Lagrange multiplier is an important method to solve conditional extreme problems. This paper gives a new method to deduce the Lagrange multipliers by using the symbolic-graphic combination method,which is more intuitive than pure algebraic method in the textbook.
