| Abstract: | Some high school students always are perplexed and at their wits' end when they do some exercises about the continue product of same kind trigonometric functions. It will make students lose their courage and interests in mathematics study. To build up students' self-confidence and creative ability, the author attempt to find a way to solve the problem by use of the tripling-angle formulae, and many a example are given in the article to explain how to appropriate use the tripling-angle formulae. |
