about parameter variations of trigonometric functions
an application
Keywords:
Technology. Trigonometric Functions; Geogebra. Winplot.Abstract
Technological evolution is a fact in all areas of knowledge, and this extends to the software used to learn and teach Mathematics. In mid-2007, a paper was produced, which proposed activities on trigonometric functions that should be solved using Winplot software. Thus, this article aims to carry out a re-reading of some activities present in that research, using the GeoGebra software to solve them. When carrying out this update, it is clear that there is a need to think about activities in order to make the student autonomous and it is expected to present teachers with the possibility of carrying out activities using software accessible to everyone.
