To find the cofactor of a certain entry in that determinant, follow these steps: Take the values of i and j from the subscript of the minor, Mi,j, and add them. Take the value of i + j and put it, as a power, on −1; in other words, evaluate (−1)i+j.

Created by Sal … WebThis is a 3 by 3 matrix. And now let's evaluate its determinant. So what we have to remember is a checkerboard pattern when we think of 3 by 3 matrices: positive, negative, positive. So first we're going to take positive 1 times 4. So we could just write plus 4 times 4, the determinant of 4 submatrix. WebOne method of finding the determinant of an nXn matrix is to reduce it to row echelon form. It should be in triangular form with non-zeros on the main diagonal and zeros below the diagonal, such that it looks like: [1 3 5 6] [0 2 6 1] [0 0 3 9] [0 0 0 3] pretend those row vectors are combined to create a 4x4 matrix. biniyam and ariela married
