This book was written to serve as a guide for students in higher education studying complex functions. A good knowledge of complex number operations, as acquired by the reader in high school mathematics, is required for its study.

The presentation of the material is particularly simple. Thus, the reader can quickly understand various concepts and methods of work.

Of course, after studying this book, one is able 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. Therefore, a good knowledge of complex functions is advantageous for engaging in these sciences.
