在工作之余仔细咀嚼2013年山东省高考数学压轴题,总是感觉味道绵长,余趣多多.笔者平时喜欢改编数学题目,下面给各位同仁展示一下改编山东省压轴题的过程,以图共勉.一、试题分析题1椭圆C:x2a2+y2b2=1(a>b>0)的左、右焦点分别为F1,F2,离心率为槡32,过F1且垂直于x轴的直线被椭圆C截得的线段长为1.(Ⅰ)求椭圆C的方程;(Ⅱ)点P是椭圆C上除长轴端点外的任一
In my spare time chewing math finale in Shandong Province in 2013 college entrance examination, always feel the taste of long, more than a lot of fun I usually like to math topics, the following to show you my colleagues in the adaptation of the topic of finale in Shandong Province in order to encourage each other. First, the test questions 1 elliptical C: x2a2 + y2b2 = 1 (a> b> 0) left and right focus F1, F2, respectively, eccentricity 槡 32, over F1 and perpendicular to the x-axis of the line is elliptic C The length of the section taken is 1. (Ⅰ) Find the equation of elliptic C; (Ⅱ) P is the point on ellipse C except the end of the long axis
