浅谈物理极值的几种求解方法

Brief Accounts on Some Basic Methods of Finding Solutions to Physical Limit Value

通过对物理极值问题的求解,总结出中学物理极值问题的基本规律,并归纳出解决物理极值的基本方法:建立与物理问题对应的数学模型,化物理极值问题为数学极值问题,从而用中学数学中各种求极值的方法求出物理极值.

This paper aims to summarize fundamental principles and induce basic methods of finding solutions to physical limit value through analysing sample problems.That is to establish mathematical model corresponded with physical problems and turn a physical problem into a mathematical one and find solutions to physical limit value using mathematical ways.
