圆锥曲线定义在解题中的应用

Application of taper curves in solving some problems

现行高中教材中的圆锥曲线既是教材的重要的基本内容,也是解决许多问题的一种方法。本文通过实例,从求解离心率、最值和轨迹等问题方面,讨论了圆锥曲线定义在解题中的重要性以及它的广泛应用。

The taper curve is one of the basic contents in the current teaching material of the senior high school,which is widely considered as an important approach to solve many problems.In this paper,some cases were used to discuss the fundamentality and extensive application of taper curves in solving some problems such as eccentricity,extremum and trajectory.
