§4.3.1 圆的极坐标方程班别 学号 姓名评价【学习目标】(1) 理解极坐标方程的有关概念；(2) (2) 掌握如何求圆的极坐标方程，并且要求能把直角坐标系与极坐标系的圆的方程的的异同和内在联系找出来。

【重难点】 理解极坐标方程的有关概念。

【教学过程】一、课前预习并完成复习：阅读课本P12-13（学生自主完成）1、在直角坐标系．．．．．中，已知圆心C （a ，b ），半径为r ，则圆的方程为：2、在直角坐标．．．．系中，已知圆心是原点，半径为5，则圆的方程为：3、在直角坐标．．．．系中，已知圆心C （1，0），半径为3，则圆的方程为：4、在直角坐标．．．．系中，已知圆心C （1，2），且圆经过原点O ，则圆的方程为：二、新课讲授1、曲线极坐标方程概念：在极坐标系中，如果平面曲线C 上 的极坐标中 有一个满足方程0),(=θρf ，并且坐标适合方程0),(=θρf 的点 ，那么方程0),(=θρf 叫做曲线C 的极坐标方程。

2、求曲线极坐标方程的方法、步骤和求直角坐标方程类似，(1)建立适当的极坐标系；(2)找出曲线上的动点θρ的极径ρ和极角θ的相互关系；(3)设法用ρ和θ的方程表示这种关系；(4)化简并证明所得的方程是所求的极坐标方程。

求曲线极坐标方程关键是找出曲线上的点满足的几何条件。

常用解三角形的知识来建立ρ和θ的关系。

注意ρ和θ的取值范围与题设条件。

三、典型例题例1、在极坐标平面内，已知圆心)0,(aC，半径为r，求其极坐标方程。

例2、已知圆心O的半径为r，建立怎样的极坐标系，可以使圆的极坐标方程更简单？四、课堂练习1、在极坐标系．．．．中，求圆心在点C（3,0），且经过极点的圆的极坐标方程．．．．．。

π），半径为2的圆2、在极坐标系．．．．中，求圆心C（2, 2的极坐标方程．．．．．。

3、课本P15 1（1）（3）五、课堂小结常见圆的极坐标方程：(1)圆心在极点，半径为r的圆的极坐标方程；(2)圆心在位于)0,(a C ，半径为r 的圆的极坐标方程 ；(3)圆心在位于)2,(πa C ，半径为r 的圆的极坐标方程 ；六、课后作业在极坐标系中，求适合下列条件的圆的极坐标方程：(1)圆心在)4,1(πA ，半径为1的圆； (2) 圆心在)23,(πa B ，半径为a 的圆。
