This method to calculate the determinant of a 3×3 matrix is called the cofactor expansion method. Remember that to find the determinant of a 2×2 matrix, you have to multiply the elements on the main diagonal and subtract the product of the elements on the secondary diagonal. Example of the determinant of a 3×3 matrix
You've got some matrix A. · It's too big to find by the simpler methods, so you'll have to find it by "expanding along a row or column". · Your first step in this ...
