Lecture

Complex Numbers: Introduction and Operations

Description

This lecture introduces complex numbers, showing that the equation x² = 2 has no solution in rational numbers, leading to the introduction of the symbol 'i' such that i² = -1. It covers the three forms of complex numbers, including Cartesian, polar, and exponential forms, and explains how to find the argument of a complex number using Archimedean functions.
