Abstract (English):
The textbook is prepared on the basis of lectures on mathematical analysis given by the author. The mathematical formalism of the presentation of classical textbooks is not suitable for the perception of a modern student, so the material is presented in a concise and more accessible form for assimilation. Meets the requirements of the federal state educational standards of higher education of the latest generation. For undergraduate students studying in the areas of "Information Systems and Technologies" and "Computer Science and Computer Engineering".
