Sal solves the problem x^3 = 1 for all of the real and complex roots using the exponential form of the complex number. He shows how the roots found in exponential form are the same as those in a more traditional form of a complex number...

This video gives an excellent overview of the different representations of a complex number. First, Sal reviews a pictorial representation of a complex number as an Argand diagram, then shows how to find the modulus and the argument of a...

In this Argand plane worksheet, students map problems dealing with theoretical aerodynamics to represent cross-sections of airfoils. They use Joukowsky mapping to sketch the image of a circle and compute the limits of a function. This...

In this Argand Plane worksheet, students use inversion mapping to sketch images of a circle in the Argand plane. This two-page worksheet contains five problems.
