Unformatted text preview: Section 8.5 Introduction to Polar Coordinates I. Introduction A _________________ coordinate system is formed by drawing a horizontal ray. The ray is called the ______________ _______________, and the endpoint of the ray is called the __________________. A point ) , ( r P in the plane is located by specifying a distance _______ from the pole and angle measured from the polar axis to the line segment OP. The angle can be measured in degrees or radians. Example 1: Plot the points on the polar coordinate system. a. (2, 11 /4) b. (1, /3) c. (4,0) In a rectangular coordinate system, there is a onetoone correspondence between the points in the plane and the ordered pairs (x,y). This is not true for a polar coordinate system! Infinitely many ordered pairs correspond to each point in a polar coordinate system. Example 2: Find another polar representation of the point (4, /6)....
