用数学方法求物理极值,就是对物理问题侧重从数学角度揭示极值条件,进而计算出有关的极值.运用这种方法突出了问题的数学意义,有利于提高学生运用数学工具解决物理问题的能力.由于在求解时直接运用了有关的数学定理,所以往往显得比较明快简捷.运用数学方法求物理极值问题的关键步骤是:(1)根据物理规律列方程,将物理问题转化为数学问题:(2)针对所建立的数学方程,利用数学中的有关定理求极值;(3)将数学问题
The use of mathematical methods for physical extremum is to focus on revealing the extreme conditions from the mathematical point of view of the physics problem, and then calculate the relevant extremum. Using this method to highlight the mathematical significance of the problem, help students improve the use of mathematical tools to solve physical problems The ability to use the relevant mathematical theorems directly in the solution, so it is often relatively simple and quick. The key steps to use mathematical methods to solve the problem of physical extremes are: (1) according to the physical laws of the equations, the physical problems into mathematics Question: (2) For the established mathematical equations, use the related theorem in mathematics to find the extremum; (3) To solve the mathematics problem
