Complex Numbers and their Polar Form

In this module, complex numbers are represented in terms of polar coordinates. This representation helps in evaluating complex number arithmetic, particularly their powers and roots as an application of DeMoivre's Theorem.

Learning Objectives:

  • Complex number - real and imaginary part
  • Complex Plane
  • Modulus and Argument of a complex number, and their properties
  • Polar form of complex number
  • Euler's Formula for a complex number
  • Products, Powers and Quotients of complex numbers, DeMoivre's Theorem
  • nth roots of complex numbers
