Learn how to represent complex numbers in polar form! In this video, we’ll build the graph of a complex number using polar coordinates, develop the formulas for r (magnitude) and θ (argument), and work through a step-by-step example converting from rectangular form to polar form.
You’ll also see how to use the Desmos scientific calculator to compute the inverse tangent for finding the angle. Perfect for algebra, precalculus, and early college math students who want to strengthen their understanding of complex numbers.
