How to convert a point from rectangular coordinates to polar

The video tutorial explains how to convert rectangular coordinates to polar format by calculating the radius and angle Theta. It covers the use of the Pythagorean theorem to find the radius and the tangent function to determine Theta. The tutorial also discusses the use of inverse tangent and radians to adjust the angle, providing a comprehensive guide to coordinate conversion.
