The Book of Mathematics . Collection of thematic tasks with samples of solutions. At 3 p.m.. H. 1: Linear Algebra. Analytical Geometry by J. A. A black man is an indispensable assistant for students, schoolchildren and anyone who seeks to deepen their knowledge in the field of mathematics. In the first volume of this extensive collection, readers will find carefully selected assignments that cover key topics of linear algebra and analytic geometry. The collection not only offers tasks, but also includes sample solutions, which makes it an ideal tool for self-study. Each task is illustrated with a clear and understandable solution, which allows the reader not only to check their answers, but also to understand the decision process. This is especially important for those who are preparing for exams or want to strengthen their knowledge before entering the university. Who can like this book? First of all, it will be useful for students of mathematical and engineering specialties, as well as schoolchildren studying mathematics at an in-depth level . Teachers and tutors will also find valuable materials in it to train their students. In addition, the book will be of interest to anyone who seeks to develop analytical thinking and learn how to apply mathematical methods in various fields of science and technology. The topics raised in the collection are fundamental to understanding more complex mathematical concepts. Linear algebra, which studies vectors, matrices, and systems of linear equations, is the basis for many applied disciplines such as physics, economics, and computer science. Analytical geometry, in turn, helps visualize mathematical ideas and apply them to real-world problems such as design and modeling. The book of the Black is distinguished by its clear and accessible style of presentation .. The author, known for his ability to explain complex topics in simple language, focuses on an intuitive understanding of the material. This allows the reader not only to memorize formulas and rules, but also to be aware of how they are applied in practice. In addition, G. A. Chernyak is the author of other well-known textbooks and collections, which confirms his high level of professionalism and deep understanding of the subject. Collection "Mathematics .
