Learn how to convert an equation from polar to rectangular format

The video tutorial explains how to convert polar equations into rectangular form for graphing. It begins with an introduction to polar equations and their limitations in graphing directly. The teacher then explains the differences between rectangular and polar forms, using trigonometric identities and the Pythagorean theorem. The conversion process is demonstrated step-by-step, showing how to manipulate the equations to express them in terms of x and y. Finally, the tutorial concludes with deriving the rectangular equation and hints at graphing techniques, such as completing the square.
