Trigonometry: Students
built 648 days ago
Trigonometry uses the techniques that students have previously learned from the study of algebra and geometry. The trigonometric functions studied are defined geometrically rather than in terms of algebraic equations. Facility with these functions as well as the ability to prove basic identities regarding them is especially important for students intending to study calculus, more advanced mathematics, physics and other sciences, and engineering in college.

Trigonometry and calculus problems from a variety of sources, including textbooks, math contests, NCTM books, puzzle books, and real-life situations, designed to reflect different levels of difficulty. From 1998 until 2002, the goal was to challenge students with non-routine problems and encourage them to put their solutions into words. Different types of problems were used to reach a diverse group of calculus students.

This mathematics educational software series ... contains Trigonometry 1 and Trigonometry 2 which together form a complete course and can be used to prepare for the CLEP exam or prepare for college math placement exams. College precalculus help is available in each of these software titles. Concentrated learning of Trigonometric functions provides the student with ample practice to form a solid understanding of Trig. Each of these two Trig programs concludes with a 30-question test with hints and complete solutions accessed upon student request.
