Imaginary

Imaginary numbers are a type of number used in mathematics to work with square roots of negative numbers. They are expressed as multiples of the imaginary unit, denoted as "i," where \(i^2 = -1\). While real numbers represent quantities like distance or quantity, imaginary numbers extend this concept to solve equations that have no solutions within real numbers alone. Together, real and imaginary numbers form complex numbers, enabling a broader range of mathematical analysis, particularly in engineering, physics, and signal processing. Imaginary numbers are a vital mathematical tool, not just a concept but an essential part of advanced problem-solving.
