Utilizando Geogebra em sala de aula no estudo de transformações aplicadas às funções trigonométricas

Abstract

In this work we will present a project developed for the High School. We will show in elapsing of this work as the re ection transformations, translation and dilation (compression) they a ect the graphs of the functions in a general way, until we arrive to the study of the trigonometrical functions. All the graphs presented in this work were obtained with the use of the Maxima and the activity in classroom was developed using Geogebra. The main idea of our work is to do with that the students initially make the activities in classroom and later using the resources computacionais makes a veri cation of the obtained results, we will divide the students in groups and to accompany the income of each group.
