This book, written by a group of authors under the leadership of Academician I. M. Gelfand - one of the greatest mathematicians of the XX century, is designed to refute the popular opinion of trigonometry as a boring and incomprehensible section of the school course of mathematics. The reader is invited to look at a familiar subject in a new way. The presentation, accompanied by a large number of problems, starts from scratch and reaches material that goes quite far beyond the school program; trigonometric formulas are illustrated with examples from physics and geometry. A separate chapter is devoted to typical techniques for solving trigonometric problems offered at the Unified State Examination. The book will be an indispensable assistant for high school students, teachers, parents and all those interested in mathematics. The previous edition was published in 2017.
