A Visual Intro to Complex Numbers

The article provides a visual introduction to complex numbers, explaining that a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, which is defined as the square root of -1. The article uses geometric and algebraic methods to help readers understand how to add, subtract, multiply, and divide complex numbers. It also explains how to plot complex numbers on a coordinate plane and how to convert between rectangular and polar forms. The article concludes with a visual representation of complex numbers, comparing them to vectors in 2D space.
