Funções trigonométricas no ENEM com o auxílio do Geogebra

Abstract

The use of digital technology, for years, has been increasingly part of students' daily lives and, therefore, the role of the teacher is increasingly challenging. In order to promote more attractive classes, the teacher takes on a new role. In today's times, the educator needs to provide their students with diversified classes that make effective use of digital technology, and present the content in an interdisciplinary and/or contextualized way, in order to place the student at the center of teaching-learning process, stimulate and challenge them. In the midst of this context and in order to assist teachers in addressing the theme of Trigonometric Functions, so present in ENEM and with applications in various areas, such as Physics and Music, from the use of digital technologies, was used the software Geogebra for building graphs of various functions, in addition to preparing lists of exercises taken from ENEM. For each ENEM question chosen, guiding questions were asked, which can be answered with the help of investigating the changes suffered in the graph of a function when we change its formation law, with the help of graphs created in Geogebra, which make use of controls that can be accessed at any time by students and teachers from the links and the blog that have been made available, making it possible to have a measure of the issues to resolve. Thus, it is expected that the class has a more investigative character, with the student at the center of the process, facilitating their understanding and learning
