中学物理教学中极值问题的处理方法

Mothod for dealing with the maximum and minimum number in middle school physics teaching

由于受数学知识的限制 ,在处理中学物理中极值问题时 ,不可能应用高等数学中函数求导的方法来处理 ,本文总结了几种应用初等数学知识处理极值问题的方法。

Limited by the knowledge of math in middle schools, the students are not able to deal with the problem of the maximum and minimum number with the changing rate of two numbers in the functions in advanced math. So the writer suggests several methods to work out the maximum and minimum number with junior math's knowlodge.
