去年高考数学(理科)试题第6题是一道应用极坐标求动点轨迹方程的题目,由于在近年高考试题中,列入这类问题还是第一次,因此更显得这一问题的重要,为使中学生能够熟悉极坐标法在解题中的作用,本文现将应用极坐标求动点 Last year, the sixth question of the mathematics (science) test of the college entrance examination was a question of applying the trajectory equation of the polar coordinate seeker point. Since this type of question was listed for the first time in the examination questions in recent years, it is more important for this question. To enable middle school students to become familiar with the role of polar coordinates in solving problems. This paper will now apply the polar motions
