WebTranscript. One thing that determinants are useful for is in calculating the area determinant of a parallelogram formed by 2 two-dimensional vectors. The matrix made from these two vectors has a determinant equal to the area of the parallelogram. Area determinants are quick and easy to solve if you know how to solve a 2x2 determinant. WebMar 25, 2024 · det(M) = Area, where the determinant is positive if orientation is preserved and negative if it is reversed. Thus det(M) represents the signed volume of the parallelogram formed by the columns of M. 2 Properties of the Determinant The convenience of the determinant of an n nmatrix is not so much in its formula as in the …
