数学轨迹方程的解法,有待定系数法、直接代换法、向量法、参数法、代入法等等。本篇文章重点讲了待定系数法、直接代换法、间接代入法、引参消参法这四种。通过对这几种常用解法的分析,我们可以更加深刻地理解和把握轨迹方程这一问题,在做题过程中选择更合适的解题方法。 Mathematical trajectory equation solution, to be determined coefficient method, direct substitution method, vector method, parameter method, substitution method and so on. This article focuses on the undetermined coefficient method, direct substitution method, indirect substitution method, cited the reference to eliminate the four parameters. Through the analysis of these commonly used solutions, we can understand and grasp the problem of trajectory equation more deeply and choose a more suitable solution to the problem.
