O estudo de problemas de otimização com a utilização do software GeoGebra

Abstract

This work presents activities that can be carried out with the High School classes and that do have basic notions of the functions, area, volume and means inequality. We present a didactic sequence, composed of several activities, with the use of GeoGebra software, so that in each of them the student can conjecture an optimization result in a classroom application. In some activities aim the elaboration of a file of type .ggb to discover an optimal value for a certain geometric element. In each activities we seek to optimize geometric elements such as segments, angles, areas and volumes. By performing these activities, students will learn geometry contents dynamically and this will provide them with a view next of what actually occurs in search to optimize of elements such geometric elements. This study aims to show that optimization problems can be worked on in High School and the results found in resolutions of these problems are demonstrated with theorems involving mathematical contents of Basic Education.
