本文笔者对2011浙江卷一道高考压轴题进行了分析解读,认为分离参数解决恒成立问题的基本思路在综合性问题中是有效的,当然这种方法不是万能的,但它能为学生提供一个思考方向,导数是高中数学和大学数学衔接的内容,近几年的高考题中导数题的综合性加强,在教学中要强化导数工具在研究函数性质中的应用,拓展学生的思路,提高学生解决综合问题的能力。
In this paper, the writer analyzes and analyzes a Zhejiang college entrance examination in 2011, and thinks that the basic idea of separating parameters to solve the problem of permanent establishment is effective in comprehensive problems. Of course, this method is not a panacea, but it can provide students with a thinking Direction, derivative is the high school mathematics and university mathematics convergence of content, in recent years, the synthesis of derivative questions in the college entrance examination to strengthen the application of derivative tools in the study of the nature of the function, to expand student ideas and improve student solutions Ability to synthesize problems.
