摘要
在平面解析几何中,定值问题一向是圆锥曲线问题中的重难点之一,经常出现在历年的高考卷中,学生在面临此类问题时,往往会遇到不知如何下手以及不知该如何套用韦达定理等问题,本文针对这些问题总结了两个具体的解题思路,希望可以减轻学生解决此类问题时面临的困难。
Abstract
In Plane Analytic Geometry, Problems about definite value have always been one of the emphasis and difficulties of conic section problem, frequently appearing in college entrance examination over the years, when students face such problems, often encounter many problems such as how to start solving such problems and how to apply Vieta Theorem and so on, this paper summarizes two specific resolving ideas of these problems, hoping it can alleviate the difficulties faced by students when solving such problems.
