"Mathematical Analysis" . Functions, Limits, Series, Chain Fractions" by Danilov B. L. , Ivanova A. N. , Isakova E. K. , Lusternik L. A. and others - this is not just a textbook, but a real treasure trove of knowledge for all who seek to better understand the basics of mathematical analysis This publication will be an indispensable assistant for both students studying mathematics in the faculties of natural sciences and engineering, and for teachers who want to update their knowledge and methodological approaches. The book covers a wide range of topics, ranging from functions and limits to rows and chain fractions. The authors have carefully worked out the material to present it in an accessible and logical form. Each chapter is filled not only with theoretical foundations, but also with practical examples, which allows the reader not only to memorize formulas, but also to be aware of their application in real-world problems. This book will be an excellent tool for those who are ready to plunge into the world of mathematical analysis, as well as for those who want to refresh their knowledge. One of the key topics raised in the book is the concept of limit the basis of mathematical analysis. The authors explain how limits help in understanding the behavior of functions, which is important for further study of derivatives and integrals. The reader will find many examples that will help to consolidate the material and develop intuition in solving problems. In addition, the book discusses series that play an important role in mathematics and its applications, from physics to economics. The book also touches on the topic of chain fractions, which makes it especially interesting for those who want to deepen their knowledge in this area. Chain fractions have many applications, including numerical methods and number theory, and their study opens new horizons in the understanding of mathematics. The authors share their knowledge and experience, which allows the reader not only to learn the material, but also to see its practical application. This book will be especially useful for senior students, graduate students and teachers, as well as for anyone who is interested in mathematics and wants to systematize their knowledge. It is suitable for both self-study and for use in the educational process. Due to its style of presentation and structured approach, the book will be an excellent addition to any training course in mathematical analysis. Authors, including such famous names as Danilov and Lusternik, have rich experience in teaching and writing educational literature. Their previous works were also popular and recognized, which indicates a high level of preparation of the material. The style of presentation is clear and logical, which makes complex topics easy to understand. If you are looking for a high-quality mathematical analysis manual that will help you not only to master the theory, but also to learn how to apply it in practice, then "Mathematical Analysis. Functions, limits, rows, chain fractions" is exactly what you need. This book will be your reliable companion in the world of mathematics and will help you confidently walk the path of knowledge. Do not miss the opportunity to discover new horizons and deepen your knowledge in mathematical analysis!
