摘要
轨迹方程的求法是解析几何知识的综合运用,其方法有很多种。参数是数学中解决问题的重要桥粱和工具,在求解轨迹问题时能发挥重要作用。本文从轨迹方程和函数图象的区别入手,从求轨迹方程的多种方法中,重点阐述利用参数法求动点轨迹方程的方法,揭示其规律。
Methods for fmding the trajectory equation is the integrated use of knowledge, analytic geometry, and its methods there are many. Parameter is an important problem in mathematics bridge and tools for solving the trajectory problem can play an important role. This article first images from the track the difference between equations and functions starting from the requirements of many ways to trace equations, using parameters of Method focuses on the fixed point locus equation approach, reveal the law.
