Complex Numbers

Complex numbers represent a fascinating aspect of mathematics, comprising both a real component and an imaginary component. Usually presented in the format 'a + bi', 'a' signifies the real component, while 'b' indicates the imaginary component, with 'i' symbolizing the square root of -1. Complex numbers play a pivotal role in higher-level mathematics and physics.
