Description: This bilingual problem-solving mathematics software allows you to work through 84102 trigonometric problems with guided solutions, and encourages to learn through in-depth understanding of each solution step and repetition rather than through rote memorization. The software offers tasks on simplification and evaluation of trig expressions, proofs of trig identities and solutions of trig equations. All the basic trigonometric and inverse trigonometric functions are included. Each solution step is provided with its objective, related definition, rule and underlying math formula or theorem. A translation option offers a way to learn math lexicon in a foreign language. Test preparation options facilitate development of printable math tests and homeworks, and automate preparation of test variants around each constructed test. A number of variant tests are ready for students to review and reinforce their skills. The software supports bilingual interface and a number of interface styles. Free fully functional trial version of this program is available
