Addition and Subtraction of Complex Numbers - Complex Analysis #2

Addition and subtraction represent translations on the complex plane. In this video we first go through the basics of adding subtracting complex numbers. A process that works as you would expect if you treat "i" as a simple constant. Then we start investigating adding simple constants to some functions. In the process we discover learn more about reading phase portraits and 3D modular surfaces. We also come across the fundamental theorem of algebra. My aim for this series is to introduce complex analysis in a visually intuitive manner, starting with the basics of complex numbers. We will start also start visualizing some simple functions very early in the series. Don't expect much in the way of rigorous proofs and definitions, there are plenty of text books for that. Instead, this series will aim to give you some visual intuition, that I hope will make any future study easier and more enjoyable.
