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. WebThe determinant of matrix is used in Cramer's rule which is used to solve the system of equations. Also, it is used to find the inverse of a matrix. If the determinant of a matrix is not equal to 0, then it is an invertible matrix as we can find its inverse.
