Determinant and matrix multiplication
WebThe properties of determinants differed from the properties of matrices, as much as the determinant differs from the matrix. For example, in a determinant, the elements of a particular row or column can be multiplied with a constant, but in a matrix, the multiplication of a matrix with a constant multiplies each element of the matrix.

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 … WebNov 8, 2024 · Swapping rows (swaps sign of det), multiplying a row by a constant (multiplies det by that constant), or multiplying a row and then adding to a multiple of another row all …
