The expansion of a 3 x 3 determinant can be remembered by the following 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: a31 a32 a33 a31 d32 Add the downward diagonal products and subtract the upward products. Use this method to compute the determinants in Exercises. Warning: This trick does not generalize in any reasonable way to 4 x 4 or larger matrices. 4 -5
