学习解题的重要目的之一就是要学会解一类问题,触类旁通是学习解题的基本要求.近年来,圆锥曲线上任一点到两定点的距离和的最值问题越来越多,难度越来越大,在各类考试中经常出现.因此,研究一下这类问题的一般解法是必要的.按照曲线一般分类,本研究主要给出抛物线、椭圆、双曲线三类,曲线中的相关最值问题的一般结论并示例其直接应用. Learning to solve one of the important goals is to learn to solve a class of problems, analogy bypassed is the basic requirement for solving problems.In recent years, the conic curve from any point to two fixed point distance and the value of the problem more and more more and more difficult Therefore, it is necessary to study the general solution of such problems.According to the general classification of curves, this paper mainly gives the three types of parabola, ellipse and hyperbola, the most relevant correlation curve The general conclusion of the problem and examples of its direct application.
