解析几何一直是高中数学的重难点,尤以运算量大,推理论证过程繁杂而著称.以圆锥曲线为载体,考察变化中的不变量,对学生的基本运算能力、观察能力、思维能力提出了较高要求,笔者读完文[1]、[2],感受很深,对二次曲线系进行了一番研究,发现可用二次曲线系快速解决文[1]、[2]中的相关问题,帮助读者从另一种角度审视解析几何问题,文末笔者给出了这类问题的几何背景,与读者分享.一、二次曲线系的基础知识
Analytical geometry has always been a high school mathematics heavy and difficult, especially in the large amount of computation, the process of reasoning and argumentation is complicated known. Conic curve as a carrier, examines the invariant changes, the students' basic computing ability, observation ability, thinking ability Higher requirements, I read the article [1], [2], deep feelings, the quadratic curve system for some research and found that quadratic curve system can be used to quickly solve the paper [1], [2] related Problem, to help readers from another point of view to analyze the problem of analytic geometry, the author gives the geometric background of these issues, and readers to share .A, the basic knowledge of the quadratic curve system
