The book is intended as a text, appropriate for use by advanced
undergraduates or graduate students who have taken a course in introductory real
analysis, or as it is often called, advanced calculus. No background in complex
variables is assumed, thus making the text suitable for those encountering the
subject for the first time. The Elementary Theory, General Cauchy Theorem ,
Applications of the Cauchy Theory, Families of Analytic Functions, Factorization
of Analytic Functions and The Prime Number Theorem.

This note covers the following topics: Complex Numbers, Euler’s
Formula, Roots and multi-valued arithmetic, Functions from C to C, Continuity
and Limits, Analytic and entire functions, Harmonic Conjugates, Morera’s
Theorem, Taylor’s Theorem, Laurent Series and Residues.
