Polar Coordinates and Their Applications

The video tutorial introduces polar coordinates, contrasting them with rectangular coordinates. It explains how to graph points using polar coordinates, including handling positive and negative angles and radii. The tutorial provides examples of graphing points and finding multiple polar coordinate representations for a single point. It also covers graphing polar equations and calculating distances between points using the polar distance formula, with practical applications like air traffic control.

In a rectangular coordinate system, what is the point of intersection of the X and Y axes called?
