CHAPTER 17: Functions of a Complex Variable

© Peteri/ShutterStock, Inc.

In elementary algebra courses you learned about the existence and some of the properties of complex numbers. But in courses such as calculus, it is likely that you did not even see a complex number. Introductory calculus is basically the study of functions of a real variable. In advanced courses, you may have seen complex numbers occasionally (see Sections 3.3, 8.8, and 10.2). However, in the next four chapters we are going to introduce you to complex analysis; that is, the study of functions of a complex variable. Although there are many similarities between complex ...
