WebA determinant is a value that can be computed from the entries of a square matrix. It is denoted by A , where A is the matrix in question. The determinant of a matrix A is equal to the product of the diagonal entries of A, after A has been row reduced to reduced row echelon form. In other words, if we have a matrix A that looks like this: A = WebThe reduced row echelon form of the matrix is the identity matrix I 2, so its determinant is 1. The second-last step in the row reduction was a row replacement, so the second-final matrix also has determinant 1. The previous step in the row reduction was a row scaling by − 1 / 7; since (the determinant of the second matrix times − 1 / 7) is 1, the determinant …
