Polar Coordinates Basic Introduction, Conversion to Rectangular, How to Plot Points, Negative R Valu

This Precalculus video tutorial provides a basic introduction into polar coordinates. It explains how to convert polar coordinates to rectangular coordinates and how to graph polar coordinates by plotting points using the radius of a circle and the angle measured counter clockwise from the positive x axis. In addition, it explains how to convert rectangular coordinates to polar coordinates and how to provide multiple representation of polar coordinates using negative r values / radius and negative angles. This video contains plenty of examples and practice problems.
