number of polar equations that cannot be expressed clearly in Cartesian form, and vice versa, we can use the same procedures we used to convert points between the coordinate systems. We can then use a graphing calculator to graph either the rectangular form or the polar form of the equation....
Note also that after we solve for one variable (like $ \theta $), we have to plug it back in either equation to get the other coordinate (like $ r$).We also have to be careful since there are “phantom” or “elusive” points, typically at the pole. The reason these points are ...

A polar coordinate consists of an arm length and an angle. Polar coordinates can be plotted by setting a point a certain distance from the origin and then rotating it around the origin. As on the unit circle, 0° and 360° are the positive x-axis, 90° is the positive y-axis, 180°...

A parabola has its simplest equation when its focus and directrix straddle one of the coordinate axes. For example, suppose that the focus lies at the point F(0,p ) on the positive y -axis and that the directrix is the line y = -p (Figure 10.2). In the notation of the figure, ...
