“Mathematical analysis” is not just a textbook, but a real treasure trove of knowledge created by P. P. Korovkin, an outstanding Russian mathematician and pedagogue . This book will become an indispensable assistant for students, graduate students and anyone who seeks to better understand the basics of mathematical analysis and its application in various fields of science and technology. In "Mathematical Analysis", Korovkin masterfully reveals complex concepts, making them available to a wide audience. The book covers key topics such as limits, derivatives, integrals and series, and offers the reader not only theoretical foundations, but also practical tasks that will help to consolidate the material studied. Each section is imbued with logic and consistency, which allows the reader to step by step plunge into the world of mathematical analysis. This book will be especially interesting for students of technical and natural sciences, as well as for anyone who is fond of mathematics and wants to develop their analytical abilities. P. P. Korovkin appeals to the reader with understanding and respect, offering not just a set of formulas, but a whole philosophy of mathematical thinking. If you are looking for a deep and systematic understanding of mathematical analysis, then this book is your ideal choice. The topics raised in "Mathematical Analysis" go beyond the simple study of formulas and theorems. Korovkin emphasizes the importance of mathematical thinking, logic and consistency in solving problems. It shows how mathematical analysis can be applied in real life, in engineering, in physics, and even in economics. The reader will be able to see how abstract concepts become tools for solving specific problems, making learning mathematics more fun and practical. Korovkin's style is distinguished by clarity and clarity of presentation. It uses many examples and tasks, which makes the learning process more interactive and fun. Each chapter ends with control questions and tasks, which allows the reader to independently test their knowledge and confidence in the material.
