Introdução do estudo de vetores no ensino médio: um ganho significativo para o estudo da geometria analítica

Abstract

This work is a proposal for the introduction of the study of vectors in the plane and in space, in the 3rd year of high school , with the prospect of a gain for studies of analytical geometry. In the study of the discipline of analytical geometry, the Masters Course Professional Mathematics ( PROFMAT ) it was found that the introduction of the study of vectors is simple understanding and a powerful tool for Analytic Geometry, facilitating the demonstration of contents , improved visualization of the alignment condition of three points of the straight line equation and its tangent and normal in the plane and space vectors, and simplify problem solving and be able to include some content that also become more accessible using such a tool. The content of that discipline is addressed in the 3rd year of high school without the vector treatment, leaving the learning of restricted analytic geometry. We present in this study a proposal to introduce the study of vectors in high school, showing that the time spent with their introduction is rewarded with greater ease to the approach of content, problem solving and expansion of the content.
