Complex Numbers and the Complex Exponential 1. Complex numbers The equation x2 + 1 = 0 has no solutions, because for any real number xthe square x 2is nonnegative, and so x + 1 can never be less than 1.In spite of this it turns out to be very useful to assume that there is a number ifor which one ha 1.2 Functions of a Complex Variable Let S be a set of complex numbers. A function f defined on S is a rule that assigns to each z in S a complex number w. The number w is called the value of f at z and is denoted by f(z). i.e., w = f(z). The set S is called the domain of definition of f. Let w = f(z) be a complex function of the complex. The study of complex analysis is important for students in engineering and the physical sciences and is a central subject in mathematics. In addition to being mathematically elegant, complex analysis provides powerful tools for solving problems that are either very difficult or virtually impossible to solve in any other way

Introduction to Complex Analysis A. Bathi Kasturiarachi Kent State University, Stark Campus December 5, 2007 Abstract Complex Analysis is a rich area of mathematics. Its applications are numerous and can be found in many other branches of mathematics, rang-ing from ⁄uid dynamics, number theory, electrodynamics, and engineer-ing, to computer. Complex analysis involves the study of complex functions which in turn requires us to de-scribe a number of special classes of subsets of the complex plane. For any z 0 2C and r>0, the set D(z 0;r) := fz2C : jz z 0j<rgis the set of all points that lie inside the circle centred at z 0 with radius rin the complex plane. This set is called the.
