The calculator will find the determinant of the matrix (2x2, 3x3, 4x4 etc.) using the cofactor expansion, with steps shown.. To find this matrix : First write down a skew symmetric matrix with arbitrary coefficients. Then compute it's determinant (which will end up being a sum of terms ... 939c2ea5af
