No. of bitstreams: 1 sampaio_r_me_sjrp.pdf: 1130997 bytes, checksum: 82f22c665b2241146e03d978ffb2e926 (MD5) Previous issue date: 2018-03-01 / Os sistemas de equações lineares são muito úteis, pois podem modelar matematicamente diversos problemas em Estatística, Física, Química, Engenharia, Administração, Economia, enfim, em várias áreas do conhecimento. Historicamente, o cálculo de soluções desse tipo de sistema pelos chineses motivou o surgimento das matrizes, que, grosseiramente falando, são tabelas de elementos distribuídos em linhas e colunas. O uso de matrizes facilita o estudo e também a resolução de sistemas lineares, pois simplificam a notação e padronizam os procedimentos. O método do escalonamento de matrizes, por exemplo, é uma técnica que pode ser utilizada em sistemas lineares em geral, além de ser facilmente automatizada devido ao seu algoritmo. O objetivo deste trabalho é apresentar alguns conceitos e resultados sobre matrizes e sistemas lineares e abordar a relação entre eles, além de propor alguns problemas que podem ser resolvidos utilizando esses resultados. Professores do Ensino Médio podem utilizar tais problemas em sala de aula para trabalhar esse assunto com seus alunos. / The systems of linear equations are very useful because they can mathematically model several problems in Statistics, Physics, Chemistry, Engineering, Administration, Economics, and finally, in various areas of knowledge. Historically, the computation of solutions of this type of system by the Chinese motivated the emergence of matrices, which, roughly speaking, are tables of elements distributed in rows and columns. The use of matrices facilitates the study and the resolution of linear systems because they simplify the notation and standardize the procedures. The Echelonment method, for example, is a technique that can always be used in linear systems in general, besides being easily automated due to its algorithm. The objective of this work is to present some concepts and results about matrices and linear systems and to approach the relation between them, besides proposing some problems that can be solved using these results. High school teachers may use such problems in the classroom to work on this subject with their students.
