Uma proposta de estudo de funções trigonométricas e suas inversas através do GeoGebra

Abstract

In this work we present tools that enable a better approach of the trigonometric functions and their inverses. In order to motivate the study of these functions we report the application of an experiment done in high school classrooms, this study can also serve to substantiate the preliminary concepts. For dynamic visualization of graphics of these functions we used the Geogebra software. We provide tutorials of the constructions of dynamic graphics in a simpler form than those found in the Geogebratube. We include the construction of an animation of a Ferris wheel to correlate to the practice developed during the experiment.
