The expansion of a 3x3 determinant can be remembered by this device. Write a second copy of the first two columns to the right of the matrix, and compute the determinant by multiplying entries on six diagonals. Add the downward diagonal products and subtract the upward products. Use this method to compute the following determinant. -1-4-5 5 0 0-1 1 3 -1-4-5 5 0-1 0 1 3 Cine 11 21 12 13 11 12 22 23 21 22 31 32 33 832
