The book "Analytical geometry" under the authorship of a team of authors, including A. N. Ostilovsky is a unique work that immerses the reader in the world of geometric concepts and their analytical description. This edition will be a real find for students, teachers and anyone interested in mathematics and its applications in various fields of science and technology. Analytical geometry is not just a set of formulas and theorems, it is a whole philosophy that allows you to see the world through the prism of numbers and coordinates. The book discusses basic concepts such as vectors, lines, and planes in space, as well as their relationships and properties. The reader will be able to learn how to use the coordinate system to describe geometric shapes, analyze them and solve complex problems. Each section of the book is carefully worked out, which allows not only to assimilate the material, but also to develop logical thinking and analytical abilities. This book will be useful not only for students of technical and mathematical specialties, but also for anyone who wants to deepen their knowledge in the field of geometry. It is suitable for both students preparing for exams and graduate students engaged in scientific research. Teachers will find in it rich material for the preparation of lectures and seminars, and lovers of mathematics will be able to enjoy immersion in the fascinating world of analytical geometry. The topics raised in the book cover a wide range of issues, from the basics of coordinate geometry to more complex concepts such as curves and second-order surfaces. Particular attention is paid to practical tasks, which allows the reader not only to theoretically master the material, but also to apply it in practice. The book also contains many illustrations and graphs that make the perception of information more visual and accessible. The style of the authors is distinguished by clarity and accessibility of presentation, which makes the material understandable even for those who are just beginning to get acquainted with analytical geometry. Each section ends with tasks for self-control, which allows the reader to test his knowledge and consolidate what he has learned. In addition, the book provides examples from real life that show how analytical geometry is applied in various fields, from architecture to physics. If you are looking for literature on analytical geometry, which will help you not only understand the theory, but also learn how to apply knowledge in practice, then “Analytical geometry” will be an excellent choice. This edition will also be useful to those who are interested in mathematics as a science and want to understand how geometric concepts affect our perception of the world around us. In conclusion, it is worth noting that the book "Analytical Geometry" is not just a textbook, but a whole world in which it is worth diving. It opens doors to the world of mathematical research and inspires new discoveries. If you want to develop your analytical skills and deepen your understanding of geometry, this publication will be your reliable companion in this fascinating journey.
