The calculus of real numbers can be extended to complex numbers, where the definitions and techniques one learns in calculus carry over to complex variables.
David C. Kay, who has written several books geared for college students, explains this development in his new book. A short review of basic concepts from real variable calculus appears with each new topic. Differentiation and integration in complex variables is clearly explained, with numerical examples.
Other topics include infinite series of complex variables, uniform convergence, the Taylor and Laurent series, and methods for evaluating difficult integrals.
Charts, tables, and drawings throughout the book make even tough concepts easy to understand, and problems have been carefully crafted to cover the main concepts while maintaining your interest.
Whether you're an educator seeking to provide an additional resource for your students or a student seeking a self-help guide to understand complex variables, the developmental in this book is a refreshing treatment that can be a stand-alone tutorial or companion guide to another textbook.
