Section   Polar coordinates
Consider a point in the  plane.
We call this point the pole (or the origin) and label it
We draw a ray extending from in any direction (but is usually drawn extending rightward).
We call this the polar axis .
If is any other point in the plane, we let be the distance from  and we let be the
angle (usually in radians) between the polar axis and the line 
The point is represented by where are the polar coordinates of
We continue the convention that an angle in the counter-clock wise direction is positive, and
negative in the clockwise direction.
