常见最值问题与恒成立、存在性问题探究

The research on common maximum-and-minimum problem,permanence,and existence

高一函数值域后续内容有最值问题,尤其是高二命题和导数中常见用参数分离求最值的题目。教学时要重点讲清、讲透这类问题的解题方法,让学生从本质上理解这类问题的知识根源和解决方法。

Students in senior one start to learn Maximum-and Minimum after finishing the study of function value.Especially in senior two,after learning proposition and derivative,it is common for students to get maximum and minimum by using parameter separation. So teachers need to focus on the solution of this kind of problem,to make students understand the essence of this problem and the general approaches to this problem.
