More about Graph Polar Coordinates and Algebra in this Mathematics Lecture. Similarly to defining a Cartesian coordinate plane by fixing two perpendicular axises, the polar coordinates are defined by a pole (a point) O and a polar axis (a ray) OA originated at the pole O. I hope this will help you. That´s what you will learn in this lesson. Also have a look at the other parts of the course, and thanks for watching.
