The book “Applied Mathematics” by Vladimir Alexandrovich Nifagin is a fascinating and deep immersion into the world of mathematical concepts that find their application in various fields of science and technology. This work will be a real discovery for students, graduate students, as well as anyone interested in mathematics and its practical aspects. Nifagin, known for its scientific works and teaching activities, offers readers a unique look at how abstract mathematical ideas can be used to solve real-world problems. The book addresses key topics such as mathematical modeling, numerical methods, statistics, and optimization. Nifagin not only expounds the theory, but also illustrates it with practical examples, which allows the reader to better understand how to apply mathematical tools in real-life situations. For example, he explains in detail how mathematical models can be used in economics to predict market trends or in engineering to optimize processes. This makes the book particularly valuable for those seeking to link theoretical knowledge with practical skills. "Applied mathematics" will be of interest not only to students of technical specialties, but also to a wide range of readers seeking to expand their horizons. If you are passionate about science, engineering, economics or even sociology, this book will help you see how mathematics permeates all aspects of our lives. It can be an excellent addition to student learning materials, as well as a useful resource for professionals who want to refresh their knowledge or master new approaches to solving problems. The topics raised in the book are relevant and important in today's world, where data and analytics play a key role in decision-making. Nifagin focuses on how important it is not only to be able to solve mathematical equations, but also to understand how these solutions can affect the real world. This makes the book especially valuable for future professionals who will work in a rapidly changing information environment. Nifagin's style is clear and accessible, which allows the reader to easily assimilate even complex concepts. His approach to learning is based on the principle that mathematics is not just a set of formulas, but a powerful tool for analyzing and understanding the world around him.
