Mastering Complex Numbers: Operations, Equations, and Graphing

The Organic Chemistry Tutor

This comprehensive mathematics tutorial provides a deep dive into imaginary and complex numbers, serving as an essential guide for high school Algebra II or Pre-Calculus students. The video begins by defining the imaginary unit 'i' and exploring the cyclical pattern of its powers. It then systematically progresses through fundamental arithmetic operations, demonstrating how to add, subtract, multiply, and divide complex numbers, with a specific focus on using conjugates to simplify quotients.
