Over 8,000 websites created by students around the world who have participated in a ThinkQuest Competition.
Our web site, accessible in both Polish and English, introduces the user to four basic trigonometric functions: sine, cosine, tangent, and cotangent. Each function is defined in the context of a right triangle and a coordinate system, with diagrams for each. Graphs of each function are also shown, and reduction formulas are given. Information pertaining to the functions as a whole include: mathematical relationships between the functions, an overview of reduction formulas, and basic trigonometric formulas. Finally two sample problems are provided to test what the user has learned.
