Solução de sistemas lineares através do método computacional para alunos da educação básica

Abstract

Systems of linear equations are a topic covered in high school so limited mainly due to the excess calculations to be made to find a whole solution. This dissertation aims to create and provide a tool for teachers who are interested in teaching find the solution of several linear systems to their basic education students using computational logic as this work contains tools for introducing the study of computational logic ally a simple programming language, accessible to students both as a regular high school for technology education. Furthermore, we present an interesting application in one of the traditional problems of chemistry, balancin reactions. In this thesis we will also address some necessary definitions and operations involving matrices. Moreover, we will see how to use a simple programming language that is used as a tool for initial learning in most courses basic programming language, the Structured Portuguese. We will point some elements of syntax VisuAlg 2.5, free compiler and auto executable that will help us achieve our goal. We will see how to find the solution of a system of linear equations with a finite number of variables using the method of scheduling systems, the backward substitution and following an algorithm for finding such a solution.
