Determinant and area of parallelogram
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. WebSimilarly, the determinant of a matrix is the volume of the parallelepiped (skew box) with the column vectors , , and as three of its edges.. Color indicates sign. When the column …
