Now we start to use the determinant. Understanding the cofactor formula allows us to show that A-1 = (1/det A) CT, where C is the matrix of cofactors of A. Combining this formula with the equation x = A -1 b gives us Cramer’s rule for solving Ax = b. Also, the absolute value of the determinant gives the volume of a box.
