Trigonometry: An analytic approach

This fifth edition reflects twenty years of classroom experience with the earlier editions. As in the previous editions, the circular functions, which are pairings of real numbers with real numbers, and their properties are introduced in Chapter 1 and are the basis for a mathematical characterization of periodic phenomena. This approach gives early importance to those aspects of trigonometry that students who plan to continue their study of mathematics will need in calculus. This edition is designed for use in a one-semester or one-quarter courses in trigonometry.
