Complex Numbers: Plotting and Polar Form

Activity Overview

This activity is designed for students who have had prior experience with complex numbers. They first refresh their memories of basic operations with complex numbers. Students then learn to plot complex numbers. Students learn the basics of writing complex numbers in their polar forms and comparing them to their rectangular form. Finally, students plot complex numbers in polar form by entering their modulus and arguments into a spreadsheet linked to a Graphs & Geometry page.
