This book was written with the aim of serving as a guide for students in higher education in the subject of complex functions. A good knowledge of operations with complex numbers, as known to the reader from high school mathematics, is required for its study.

The presentation of the material is particularly simple. Thus, very quickly the reader can understand various concepts, as well as various working methods.

Of course, after the completion of this study, one is in a position to study complex functions from a more theoretical perspective.

Complex functions are particularly useful in various fields of natural sciences, such as fluid mechanics, automatic control systems, electrostatics, etc. Thus, a good knowledge of complex functions constitutes a favorable factor for engaging in the aforementioned sciences.
