Analytical Geometry . The course of lectures with tasks” by Yuri Sadovnichy and Vladimir Fedorchuk is not just a textbook, but a real find for students, graduate students and anyone who seeks to understand the basics of analytical geometry more deeply . In this edition, the authors masterfully combine theory and practice, offering readers not only clear explanations of key concepts, but also a variety of tasks that will help to consolidate the material. Analytical geometry is the field of mathematics that studies geometric objects using algebraic methods. In the book Sadovnichy and Fedorchuk, readers immerse themselves in the world of coordinate systems, equations of lines and planes, and also study more complex topics, such as curves and second-order surfaces. Each section of the book is built logically and consistently, which makes it easy to assimilate even the most complex concepts. This book will be of interest not only to students of technical specialties, but also to everyone who wants to develop analytical thinking. If you study at the Faculty of Mathematics, Physics, Engineering or Architecture, then Analytical Geometry will become your reliable companion in the study of the subject. It is also suitable for teachers who are looking for quality materials to prepare for classes and exams. The topics raised in the book cover a wide range of issues, ranging from the basics of the coordinate system to more complex aspects, such as the properties of geometric shapes and their relationships. The authors pay attention not only to theoretical aspects, but also to practical tasks, which makes the material more accessible and understandable. Each problem is accompanied by a detailed solution that allows readers not only to test their knowledge, but also to understand how to apply the theory in practice. The style of the authors is clear and accessible. Sadovnichy and Fedorchuk use simple and understandable wording, which makes their lectures easy to understand. Their approach to learning is based on the principle that understanding the basics is the key to successfully solving more complex problems. This quality makes the book especially valuable for those who are just beginning to get acquainted with analytical geometry. In addition, Yuri Sadovnichy is a well-known Russian mathematician who has many publications and scientific works, which adds additional value to his works. His experience and knowledge, combined with the practical approach of Vladimir Fedorchuk, create a unique training manual that will be useful both for self-study and for use in the educational process. If you are looking for high-quality literature on analytical geometry, which will help you not only to master the theory, but also to learn how to apply it in practice, then "Analytical geometry . The course of lectures with tasks" will be an excellent choice. This book will not only expand your knowledge, but also help you develop analytical abilities that will be useful to you in the future. Do not miss the opportunity to immerse yourself in the fascinating world of geometry and discover new horizons of mathematical thinking!
