103 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. Basic topics include
trigonometric formulas and identities, their applications in the
geometry of the triangle, trigonometric equations and inequalities, and
substitutions involving trigonometric functions. 103 Trigonometry
Problems is a cogent problem-solving resource for advanced high school
students, undergraduates, and mathematics teachers engaged in
competition training.
