EVALUATING A 3 X 3 DETERMINANT Evaluate. expanding by the second column. To find this determinant, first get the minors of each element in the second column. Now find the cofactor of each of these minors. The determinant is found by multiplying each cofactor by its corresponding element in the matrix and finding the sum of these products.

Minor and Cofactor
