Complex Analysis is a branch of mathematics focusing on functions of complex numbers. It extends calculus concepts to the complex plane, where functions are infinitely differentiable and analytic. This field underpins many scientific and engineering applications, from AC circuit analysis to quantum mechanics. Key topics include the Cauchy Integral Theorem, residues, and holomorphic functions, all of which have profound theoretical and practical implications.
