Álgebra linear no ensino médio

Abstract

In this work, we will make a presentation of Linear Algebra in high school this alternative form. In this way, the introduction of the concepts of vector space and afine variety, which are introduced through the study of matrices and linear systems, will be proposed. Thus the arrays appear as elements of a vector space and the solution set of a linear system as an a ne variety. This text will not be addressed the idea of determinants,we believe this can be without much damage, withdrawal of the mathematical curriculum of basic education.
