Convert polar coordinates to rectangular coordinates

The video tutorial explains how to graph points using polar coordinates, focusing on converting these coordinates into X and Y coordinates. The teacher demonstrates the process of calculating the X and Y coordinates using trigonometric functions, specifically cosine and sine, and verifies the results by checking the quadrant placement. The lesson emphasizes understanding the relationship between polar and Cartesian coordinates, ensuring students grasp the concept of distance and angle in graphing.

What is the significance of the negative angle in polar coordinates?

Explain how to determine the quadrant in which a point lies based on its X and Y coordinates.
