Mathematical Analysis: Foundations of Theory . Economic Annexes: Educational and Methodological Manual" by Kruglov E. In. , Kuznetsova Yu. A. and E. Talanova A. It is an indispensable source of knowledge for students, teachers and practitioners seeking to understand the underlying mechanisms of mathematical analysis and its critical roles in economics. This book is a unique combination of theoretical foundations and practical problems, which makes it especially attractive for those who want not only to master complex mathematical concepts, but also to learn how to apply them in real economic scenarios. The authors focus on the fundamental principles of mathematical analysis, such as limits, derivatives, integrals and series, disclosed with clarity and accessibility. But the main advantage of the book is its practical orientation .. The authors demonstrate how mathematical tools help to model economic processes, analyze market trends and make informed decisions. As a result, the reader receives not only a theoretical base, but also specific cases illustrating the application of mathematical analysis in economics, which makes the book especially valuable for students of economic specialties, graduate students and young professionals. Mathematical Analysis: Foundations of Theory . Economic applications” is perfect for those who are looking for a textbook combining a strict scientific approach and an applied focus. It is designed for readers aged 16 years and older with basic knowledge of mathematics, and interested in deepening their knowledge in the field of economic mathematics. It will be especially useful for university students studying in the areas of Economics, Management, Finance and Business Analysis, as well as for teachers looking for modern and understandable material for lectures and practical classes. The style of the authors is a harmonious combination of the rigor of scientific presentation and a living, understandable language, which makes complex topics accessible even to beginners. The book is distinguished by a systematic approach, logical structure and rich illustrative material, which contributes to a deeper assimilation of the material. In their other works, such as textbooks on mathematical analysis and economic mathematics, Kruglov, Kuznetsov and Talanov have established themselves as authors who are able to explain the complex in simple language, while maintaining academic rigor. The book pays special attention to practical aspects - from the construction of mathematical models to data analysis and risk assessment. This makes it an indispensable tool for those who want not only to understand the theory, but also to learn how to apply mathematical methods to solve specific economic problems.
