Polar to rectangular equation conversion

The video tutorial explains how to convert polar coordinates to rectangular coordinates. It begins with an introduction to the concept, followed by a discussion on the R-squared relationship. The tutorial then demonstrates solving an equation to determine the radius of a circle, emphasizing the conversion process and the mathematical relationships involved.

How do you express the radius in terms of X and Y?

What is the relationship between polar and rectangular coordinates?

What equation can be derived from squaring both sides of R?

What does R-squared equal in the context of this discussion?

What shape is represented by the equation derived from the polar coordinates?
