摘　　要：利用参数方程研究问题,角度更为独特、描述运动变化更为直接,常常比普通方程便捷。本文就一类参数方程的三种常见考察方式进行研究,这三种方式各有特点,并就每种考查方式给出多种解决方法,以供读者参考。Using parametric equations to study problems is more unique and describes movement changes is more directly,often more convenient than ordingry equations.A class of parametric equations which has three common methods of investigation in this paper,each method has its own characteristics,and a variety of solutions for each type of examination was given for readers′.

关 键 词：参数方程 极坐标 直角坐标
