EMSolution_Trigonometry
	This bilingual training program offers 168767 trigonometric problems with fully explained step by step solutions and test authoring tools. Problems of 11 levels of complexity vary from basic to advanced. Considered are computational problems, proofs of identities, solutions of trig equations and more. All trigonometric and arc-trigonometric functions are included. Solution methods include universal substitution, formulas of product and addition of trigonometric functions, power reduction, multiple argument, shift of argument, and more. Each solution step is provided with the corresponding objective, definition, rule and proof of the underlying math formulae or theorem. Tutoring material is available in two languages and is always under hand. Special options help teachers create quizzes, tests, variant tests, exams and homeworks of varied complexity and develop problem solving lesson plans. 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 Company: EMTeachline Software  Date Released: 10-10-2004  Program Size: 11043 KB License: Shareware Platform: Win95,Win98,WinXP,Windows2000
