The material in the textbook is explained, with a consistent emphasis on the simplicity of the explanation and the immediate connection to the practical application of the mathematical apparatus being discussed. The textbook contains a sufficient number of solved instructional problems to cover all phenomena and exercises for practice. The arrangement of chapters in the textbook and workbook is, of course, identical, and it is assumed that the textbook and workbook will be used concurrently.

The main effort is to present the material in a readable form with an emphasis on direct connections to practice and previously covered material. The textbook uses several simple types of texts and labels to aid orientation. These include motivational texts, texts referring to...
