Aplicações de sistemas lineares voltadas ao ensino médio

Abstract

The objective of this work is to train mathematics teachers, to encourage more and more students in this area of science. The text contains a largely overlooked subject in mathematics classes, which is the linear systems solution, give in the classroom as a simple item in the menu without its importance in the student's daily life, or even in their professional lives, regardless of what area they follow. This paper is divided as follows: an introductory section of basic concepts review; the presentation of two methods for the linear systems solucion, Gauss Elimination and LU Decomposition; curve tting by least squares method; and nally, day-by-day problems with gradual increase of complexity, in order to whet the curiosity of the students for this important subject in the area of exact.
