轨迹问题是高考重点考查内容,它综合考查了学生逻辑推理能力,运算能力,分析问题、解决问题的能力。轨迹问题是解析几何的主要内容之一,在高考试题中既有选择题、填空题也有解答题,经常与三角函数、平面向量、平面几何及实际问题相联系,一般难度较大,故平时应引起足够的重视。本文对曲线方程轨迹的求法做一归纳,供 Track problem is the key content of the college entrance examination test, which comprehensively examines the student’s logical reasoning ability, computing power, analysis of the problem, the ability to solve the problem. Trajectory problem is one of the main contents of analytic geometry. There are multiple-choice questions in the entrance examination questions, fill-in-the-blank questions also have answers, often associated with trigonometric functions, plane vectors, plane geometry and practical problems, generally difficult, Caused enough attention. In this paper, we can make a conclusion about the method of calculating the trajectory of the curve equation
