# Polar coordinates - Parametric Equations and Polar Coordinates

### Polar coordinates

In this section, we will introduce a new coordinate system called polar coordinates. We will introduce some formulas and how they are derived. Then we will use these formulas to convert Cartesian equations to polar coordinates, and vice versa. We will then learn how to graph polar equations by using 2 methods. The first method is to change the polar equations to Cartesian coordinates, and the second method is to graph the polar equation using a table of values.
