[en] TRIGONOMETRY: ANGLE ADDITION FORMULAS / [pt] TRIGONOMETRIA: FÓRMULAS DE ADIÇÃO E SUBTRAÇÃO DE ARCOS

HUMBERTO GULLO DE BARROS 05 February 2015 (has links)
[pt] Trata-se de uma proposta que visa orientar o professor de Matemática do Ensino Médio em relação às dificuldades encontradas no ensino-aprendizagem da Trigonometria. Mais especificamente, para facilitar, com demonstrações alternativas, o desenvolvimento das fórmulas de adição de arcos. Para o desenvolvimento desse trabalho, optou-se pela metodologia da pesquisa documental, na qual se buscou os subsídios para o desenvolvimento da proposta. / [en] It is a proposal which aims to guide Mathematics High School teachers to cope with the difficulties faced in the teaching-learning process of trigonometry. More specifically, it will facilitate the development of arc addition formulas by the use of alternative statements. In order to improve this work, it was chosen the documentary research methodology, where the subsidies for the development of this proposal were searched.
