168767 solved trigonometric problems with test authoring tools

Test authoring mathematics software offers 168767 trigonometric problems from basic to advanced, with solutions and easy-to-use authoring options. Considered are all trigonometric and arc-trigonometric functions. Computational problems, transformation and evaluation of trigonometric expressions, proofs of trigonometric identities and solutions of trigonometric equations. A variety of solution methods is applied, including universal substitution, formulas of product and addition of trigonometric functions, power reduction, multiple argument, shift of argument, and more. The program enables users to select problems by complexity and solution methods and create math tests, homeworks, quizzes and exams of varied complexity in a minute. The program generates 20 variant tests around a constructed example. A number of variant tests are ready for students to review and reinforce their skills. Free fully functional demo version of this program is available.
