Complex Numbers: Representation and Properties

This lecture covers the representation of complex numbers in polar and Cartesian form, along with their properties. It includes topics such as the definition of complex numbers, polar representation, Euler's formula, Moivre's formula, and the properties of complex conjugates. The lecture also explores the inverse of complex numbers, the Cartesian and polar forms of complex numbers, and the applications of Euler's formula and Moivre's formula.
