在复习椭圆、双曲线和抛物线时,我们的做法是组织和指导学生从基本概念和理论、基本问题和题型、基本思路和规律、基本方法和步骤、基本运算和法则等五个方面,进行全面的归纳和整理,并配备一定数量的习题,用以巩固基础知识,熟练基本技能,提高分析问题和解决问题的能力。重点要突出:根据方程求性质,根据已知条件求曲线方程,进而研究曲线之间的相互关系。
When reviewing ellipses, hyperbolas and parabolas, our approach is to organize and guide students in five aspects: basic concepts and theories, basic problems and types of questions, basic ideas and laws, basic methods and procedures, basic operations, and rules. Comprehensive induction and consolidation, and a certain number of exercises to consolidate the basic knowledge, skilled basic skills, and improve the ability to analyze problems and solve problems. Emphasis should be given to the following: to find the properties according to the equations, and to find the curve equations based on known conditions, and then to study the relationship between the curves.
