O uso da Trigonometria como uma ferramenta para a resolução de problemas reais

Abstract

The present work aims to present applications of Trigonometry in various areas, such as Astronomy, Engineering, Topography, among others. Although trigonometry has numerous applications, those that emphasize trigonometric ideas and concepts in calculations are not easily found. A large part of the applications only show ready-made formulas. The purpose of this work is to present applications showing in its developments, the moment in which a certain trigonometric concept was used, bearing in mind that, to make learning more meaningful for students, they need to know where each result comes from. For teachers, these applications can serve as a basis for further development and can be applied in high school classes and some even in teaching classes. Fundamental. data produced during the development of field research.
