WebJan 4, 2016 · For the first minor obtaining: ( 3 0 − 4 − 8 0 3 5 0 − 6) M1 being row one column one we attain − 12 = 1. This is to be multiplied by the determinate of the minor. Now finding the determinant I did: Then: 4 times (− 8 0 5 0) giving 4(0 − 0) = 0 adding the determinants we get 0 + 0 + 0 = 0 So det M1 = 0(1) = 0. WebA determinant is a property of a square matrix. The value of the determinant has many implications for the matrix. A determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's ...
