How to Find the Determinant of a 3X3 Matrix: 12 Steps
Finding Determinant of 3x3 Matrix ~ Diagonals Method “The first step is to rewrite the first two columns of the matrix to the left of it. Next, we will be multiplying the entries along three down diagonals (the red arrows) and up three other diagonals (blue).

The determinant of transposed matrix is the same as the determinant of the original matrix: Det(AT) = Det(A). If we apply the column expansion of equation [44] to an upper triangular matrix, A, we find that Det A = a11A11, since the a11 term is the only term in the first column. We can apply equation [44] repeatedly to the cofactors.
