Funções trigonométricas no GeoGebra: discussões metodológicas

Abstract

This work addresses the importance of trigonometric functions in various areas of applied mathematics, highlighting their fundamental role in describing periodic phenomena and modeling real situations. The sine, cosine and tangent functions are essential examples of these mathematical relationships, finding application in engineering, physics, statistics and computing. The analysis of trigonometric functions is facilitated by the use of GeoGebra, an interactive and dynamic tool that combines geometry, algebra and calculus resources. GeoGebra enables comprehensive exploration of trigonometric functions, offering immediate graph views, parameter manipulation, and detailed property analysis. The justification for using GeoGebra lies in its ability to provide an engaging and accessible learning experience, contributing to the understanding and effective application of trigonometric functions. The need to explore this tool arises from the demand for a more accurate, fast and visual analysis of trigonometric functions in different mathematical and scientific contexts. The hypothesis of the study is that GeoGebra, by offering an interactive and visual approach to the analysis of trigonometric functions, is an effective tool in modeling and solving mathematical and scientific problems. We aim to investigate the impact of GeoGebra on teaching trigonometric functions and propose improvements in the learning process. In the end, we hope that this study contributes to a deeper understanding of trigonometric functions and their practical applications, highlighting the crucial role of GeoGebra as a valuable tool in the analysis and modeling of these functions in diverse mathematical and scientific contexts.
