The video tutorial explains how to convert rectangular coordinates to polar form by calculating the length R and angle Theta. It covers plotting points, using the Pythagorean theorem to find R, and applying tangent and inverse functions to determine Theta. The tutorial also discusses how calculators compute angles in different quadrants and how to interpret these results.
