Reseña del editor:

This no-nonsense guide provides students and self-learners with a clear and readable study of trigonometry's most important ideas. Tim Hill's distraction-free approach combines decades of tutoring experience with the proven methods of his Russian math teachers. The result: learn in a few days what conventional schools stretch into months.

• Teaches general principles that can be applied to a wide variety of problems.
• Avoids the mindless and excessive routine computations that characterize conventional textbooks.
• Treats trigonometry as a logically coherent discipline, not as a disjointed collection of techniques.
• Restores proofs to their proper place to remove doubt, convey insight, and encourage precise logical thinking.
• Omits digressions, excessive formalities, and repetitive exercises.
• Covers all the trigonometry needed to take a calculus course.
• Includes problems (with all solutions) that extend your knowledge rather than merely reinforce it.
