Polar to rectangular point conversion

The video tutorial explains how to convert polar coordinates to rectangular form. It begins by introducing the formula for conversion and discusses the concept of negative angles and their equivalence on the unit circle. The tutorial then demonstrates how to calculate the cosine and sine values needed for the conversion. Finally, it derives the rectangular coordinates and emphasizes understanding the unit circle.
