Determinants The determinant function associates a number with any square matrix. It is written as det(A) or A Determinant of 2 x 2 matrix a b det ( A) = = ad − bc c d − 3 − 6 1) Find the determinant of 2 − 5
Determinant of high order matrix 3 1 1 − 2 5 3 2) Find the determinant of 3 − 2 − 2
3) Use determinants to solve the system of equations x − 5 y = −6 3 x + 2 y = −1
