Métodos contemporâneos para cálculo de determinantes de ordem N > 3 e matrizes inversas de ordem 3

Abstract

In the teaching process, learning of the matrices, a subject that has as a characteristic main to be taught in the second year of high school, it was noted that the development of inverse matrices require some work and take too long to obtain. in addition to the the fact that students are able to understand the traditional method pointed out in the materials didactics. Another content covered in the second year are the determinants of square matrices in that the greater the value of the order of the matrix, the greater the work that one has to do with the calculation of the determinant. Today the big problem since high school is certainly in the matrices of order 4 that, many times, the method is not understood and therefore, teachers only minister from matrices of order 3.
