Teach Yourself Trigonometry is suitable for beginners, but it also goes beyond the basics to offer comprehensive coverage of more advanced topics. Each chapter features numerous worked examples and many carefully graded exercises, and full demonstrations of trigonometric proofs are given in the answer key.

Precalculus with Trigonometry prepares students for calculus by using methods emphasizing technology, cooperative learning, real-world applications, and student discovery to instill the concept that variables really vary. Students use the law of cosines to model the position of an orbiting satellite, rather than simply to analyze a fixed triangle. They fit functions to data, returning to recurring themes such as outer space, sports, music, aviation, automobiles, and finance as their mathematical maturity develops.

03 Trigonometry Problems contains highly-selected problems and solutions used in the training and testing of the USA International Mathematical Olympiad (IMO) team. Though many problems may initially appear impenetrable to the novice, most can be solved using only elementary high school mathematics techniques.
