Then I add the down-diagonals, subtract the up-diagonals, and simplify for the final answer: There are other methods for simplifying determinants by hand, and these other methods are required when evaluating larger determinants by hand, but those methods can probably wait until later. For the time being, note that your graphing calculator should be able to evaluate the determinant of any

Find more Mathematics widgets in Wolfram|Alpha. As another hint, I will take the same matrix, matrix A and take its determinant again but I will do it using a different technique, either technique is valid so here we saying what is the determinant of the 3X3 Matrix A and we can is we can rewrite first two column so first column right over here we could rewrite it as 4 4 -2 and then the second column right over here we could rewrite it -1 5 The determinant of is the sum of three terms defined by a row or column. Each term is the product of an entry, a sign, and the minor for the entry.
