在中学物理中,会遇到求极值问题,对中学生来说,这是比较难的问题。一方面是因为求极值要根据给定的具体条件,运用物理知识去分析,同时又要牵涉到较多较难的数学知识。但只要掌握规律,正确运用求极值的方法,也是不难解决的。本文介绍在中学物理教学中 In the middle school physics, you will encounter extreme problems. For middle school students, this is a difficult problem. On the one hand, it is because of the specific conditions given to find the extremum, the use of physical knowledge to analyze, but also involves more difficult mathematics knowledge. However, as long as we master the laws and correctly use the method of seeking extremum, it is not difficult to solve. This article is introduced in the middle school physics teaching
