高考中的最值问题是热点,也是重点,很多时候也是难点.几乎每一套高考试卷总有2个～4个不等的最值相关问题,或求最值,或已知最值求变量取值(或范围)等形式,备受命题者青睐.本文以2013年浙江高考理科卷中的最值试题为例,解析常见最值题的处理方法.第一类利用几何性质适用于最值问题有一定的几何意义,如解析几何中的最值、向量运算中的各种几何意义等.图1例1(2013年浙江理13)
The most valuable issue in the college entrance examination is the hot spot, but also the focus, in many cases is difficult.Almost every set of college entrance examination papers there are always 2 to 4 most relevant questions, or seeking the most value, or the most known variables Value (or range) and other forms, which are favored by the proponents.This paper takes the most value test questions in the Zhejiang college entrance examination science curricula in 2013 as an example to analyze the treatment methods of common most value problems.The first kind of utilization geometry is suitable for the most value The problem has a certain geometric meaning, such as analytic geometry of the most value, vector operations in a variety of geometric meanings, etc. Figure 1 Example 1 (2013 Zhejiang Li 13)
