物理学是一门精确科学,与数学有密切的关系,数学为物理学的发展提供了强有力的工具,也为应用物理规律解决具体问题开通了道路。用数学知识解决物理极值问题,不仅易为中学生所接受,而且能培养学生应用数学知识解决物理问题的能力。为此,本文介绍求解物理量极值的几种数学方法,供 Physics is a precise science and has a close relationship with mathematics. Mathematics provides a powerful tool for the development of physics and opens the way for the application of physical laws to solve specific problems. Using mathematical knowledge to solve physical extremum problems is not only easy for middle school students to accept, but also can cultivate students’ ability to apply mathematics knowledge to solve physical problems. For this reason, this paper introduces several mathematical methods for solving the extremes of physical quantities.
