Geometric Interpretations of Complex Number Operations
Complex numbers extend the realm of real numbers by introducing an imaginary unit, denoted as 'i', where i² = -1. This allows us to represent points in a two-dimensional plane, known as the complex plane. Each complex number z = a + bi corresponds to a point (a, b) on this plane. Addition and subtraction of complex numbers correspond geometrically as vector addition and subtraction, where each complex number is treated as a vector. Multiplication more info of complex numbers entails rotations and scaling in the complex plane. For instance, multiplying by 'i' rotates a point counterclockwise by 90 degrees, while multiplying by a real number scales the distance from the origin. This geometric interpretation provides compelling insights into the nature of complex numbers and their operations.
