Question
In a polar coordinate system, we select a point, called the pole, and then a ray with vertex at the pole,
called polar axis. A point P in a polar coordinate system is represented by an ordered pair of numbers
(r,0). If r> 0, then r is the distance of the point from the pole; 0 is an angle formed by the polar axis
and a ray from the pole through the point.
