Determinants of 2x2 matrix
WebMar 5, 2024 · To find the inverse of a matrix, we write a new extended matrix with the identity on the right. Then we completely row reduce, the resulting matrix on the right will be the inverse matrix. Example 2. 4. ( 2 − 1 1 − 1) First note that the determinant of this matrix is. − 2 + 1 = − 1. hence the inverse exists. WebJacobian matrix and determinant.
