A Brief Course in Analytical Geometry is not just a textbook, but a real find for anyone who seeks to understand the world of mathematics and geometry more deeply. The author, Efimov, masterfully combines theory and practice, offering readers clear and accessible explanations of complex concepts. This book will be an indispensable assistant for both students and teachers, as well as for anyone interested in mathematics and its application in various fields. The focus of the Brief Course in Analytical Geometry is on the basic concepts and methods that allow the analysis of geometric shapes using algebraic equations. Efimov not only expounds the material, but also immerses the reader in the fascinating world of geometry, where each theorem and each formula become the key to new knowledge. The book covers a wide range of topics, from the simplest concepts of dots and straight lines to more complex issues related to planes and spatial figures. What makes this book especially appealing is its structure. Each section is logically built, which allows the reader to gradually master the material. The examples and tasks proposed by the author help to consolidate knowledge and develop analytical thinking . Efimov uses a lively and accessible language, which makes even the most complex topics understandable to a wide audience. This is especially important for students who may have difficulty in perceiving mathematical concepts. The book will be of interest not only to students of mathematical and technical specialties, but also to teachers who are looking for new approaches to explaining the material. It is also suitable for those who are fond of mathematics as a hobby or want to refresh their knowledge in the field of analytical geometry.
