Polar Coordinates and Angles

The video tutorial explains how to determine four possible ordered pairs in polar coordinates for a given point. It covers the concept of polar coordinates, where an ordered pair is represented as (R, Theta). The tutorial provides examples of ordered pairs when R is positive and when R is negative, discussing the corresponding angles in both degrees and radians. It highlights the infinite possibilities of representing points using polar coordinates and provides specific examples to illustrate the concept.

What is the format of an ordered pair in polar coordinates?

• (R, Theta)

• (X, Y)
