Determinants of 2x2 matrix
WebI have read the proof for finding the determinant of a 2 × 2 matrix. It makes sense, since for a matrix (a b c d) (ad − bc) must be non-zero for the inverse of the matrix to exist. So it is logical that (ad − bc) is the determinant. WebThe determinant of a 2x2 matrix is Notice the difference in notation between the matrix and its determinant: matrices are typically enclosed with square brackets whereas determinants The determinant is a scalar quantity. in many applications. The determinant is most often used to test whether or not a matrix has an inverse
