The main purpose of esta m Second Edition is essentially the same as the primer edition with changes designated a Continuation.

“The of functions of one variable variables Also called of brevity or Analysis, it is one of the most beautiful branches, as well as useful mathematics. Despite its origins in an atmosphere of mystery, suspicion and distrust, as evidenced by the imaginary and terms in the literature, was finally placed on a solid base line 19th century through the efforts of Cauchy, Riemann, Weierstrass, Gauss and other mathematical Great “.

This book esta Designed for use as a supplement to all current texts or standards As textbook COURSE FOR A formal theory of complex variable AND APPLICATIONS. Also be of great value to those who take courses in mathematics, physics, aerodynamics, elasticity, and many other fields of science and .

Numerous problems theorems and derivations of formulas INCLUDED also on the problems solved. Each chapter begins with a clear statement of relevant nitions, principles and theorems together with illustrative material Description and Other. This is followed by sets of Graduate and supplementary Problems Resolved. The large number of additional problems with answers serve for a more complete view of each chapter materials.

Topics covered include algebra and geometry of complex numbers, calculus differential and integral Complex in finite series, including Taylor and Laurent series, the theory of waste with Applications to s evaluation of integrals and series, and Representation conforme with applications from various fields.

Some adj Of changes we made to the first edition son the Following:

(A) We have expanded and corrected many of Sections sea for more accessible Our readers para.
(B) We have changed the format of the text, for example, the number of chapters, are now included on the label of all sectors, examples and problems.
(C) Results Many formally expressed as propositions and theorems.
