近几年高中数学改革力度不断加大,新课程启动,p要求我们高中数学教师在高中数学复习中要转变教学思路,设计符合现代教学理念的高中复习课方案,让学生自觉、主动、创造性地去开展数学活动。现以圆锥曲线中的“求|(MA)~—|+μ|(MF)~—|的最值”一课为例谈谈高三数学复习课的设计:例题:已知A(-2,3~(1/3)),F是椭圆(x~2/16)+(y~2/12)=1的右焦点,点M在椭圆上移动,当|(MA)—|+2|(MF)—|取得最小值时,求点M的坐标。
In recent years, mathematics reforms in high schools have continued to increase in intensity, and new courses have been started. We urge our high school mathematics teachers to change their teaching ideas in the review of high school mathematics and design high school recitation programs that meet the modern teaching philosophy so that students can consciously, initiatively, and creatively. To carry out mathematics activities. Now take the “math~~|+μ|(MF)~-|the most value of a lesson” in the conic curve as an example to talk about the design of the third grade mathematics review class: Example: Known A(- 2,3~(1/3)), F is the right focus of the ellipse (x~2/16)+(y~2/12)=1, point M moves on the ellipse when |(MA)—|+ 2|(MF)— When the minimum value is obtained, the coordinates of the point M are determined.
