Formulas include: fundamental identities, Pythagorean identities, sum/difference formulas, sum-to-product and product-to-sum formulas, the odd/even functions, the law of sines, the law of cosines, and the half- , double- , and triple-angle formulas. It also includes a list of common values and less common values, such as 30, 45, 15, 18, and 54 degrees. Great for student preparing for pre-calculus or trigonometry quizzes, tests or exams.
