Trigonometry, a work in the collection of the Gelfand School Program, is the result of a collaboration between two experienced pre-college teachers, one of whom, I.M Gelfand, is considered to be among the most distinguished living mathematicians.

Trigonometry covers all the basics of the subject through illustrations and examples. Geometric relationships are rewritten in trigonometric form and extended, while trigonometric functions are geometrically motivated. The text then makes a transition to the study of algebraic and analytic properties of trigonometric functions, in a way that provides a solid foundation for more advanced mathematical discussions. Throughout, the treatment stimulates the reader to think of mathematics as a unified subject.

There is no teacher's guide, workbook or answer key for this book. Solutions are provided for some of the problems. 229 pages, paperback.
