      1. How Polar Coordinates Work

      In CartesianCoordinates:  the position of a point inthe plane is(x, y)。Polar coordinates use the idea of describing the positionof a point P by giving its distance r from the origin and the angle θ betweenOP and the positive x-axis. The angle θ is positive in the anticlockwise sensefrom the initial line. If it is necessary to specify the polar coordinates of apoint uniquely then:





      2. ThePolar Equation of a Curve


      好,下面我来举个例子,米娜桑们感受一下:


      3. Generalshapes

      好,了解了polar coordinates的表示方法后,小编为大家总结一下常见的polar coordinates的图像。





      4. TheArea of a Sector


      Thearea of the sector shown in the diagram is:


      这部分只是简单的计算,小伙伴们注意不要算错即可。那么,我来举道例题,小伙伴们可以?#23548;识?#25163;算一下。

      SolutionThe area is clearly twice the area of the sector given by:



      5. Tips
      画?#38469;?#35201;看清楚题目中要求画的curve的角度范围,注意标记initial line和origin.
      基本定义(r, θ),长度在前,角度在后
      求面积时要看清楚题目中要求求得sector area的角度范围
      以上就是今天polar coordinates的讲解了,知识点不是很多,但是确实高数中比较容易出错的一节,小伙伴们就多加理解和练习哦!
