《圆锥曲线》是解析几何中的主要内容,也是高中数学的重点内容.在历年高考数学试题中占的比重较大,题目综合性较强,它蕴含着数形结合,等价转化,分类讨论,函数与方程等数学思想方法;问题涉及函数、方程、不等式、三角、平几等方面知识.我们在学习过程中要学会从学科的整体高度考虑问题,在知识网络交汇点思考问题.下面,笔者结合自身的教学经验介绍几种利用平几知识妙解圆锥曲线问题的方法供同学们参考.
“Conical curve” is the main content of analytic geometry, and it is also a key content of high school mathematics. It has a larger proportion of mathematics test questions in college entrance examinations over the years, and has a more comprehensive topic. It contains the combination of number and shape, equivalent transformation, classification discussion. Mathematical thinking methods such as functions, equations, etc.; issues involving functions, equations, inequalities, triangles, flats, etc. We must learn to consider issues from the overall height of the discipline in the learning process, and to consider issues at the intersection of knowledge networks. The author introduces several kinds of methods that use the knowledge of solving the conic curve problem with reference to the students.
