Determinant of a matrix is zero

WebThe matrix of the determinant is non-singular and not invertible. The matrix of the determinant may be a zero matrix. The system of equations associated with the matrix is linearly dependent. The rows and columns of the matrix of the determinant are linearly dependent vectors. Example: A = 1 2 3 2 0 2 0 5 5 The determinant of A is, WebSolution Conditions when the determinant can be zero: There are three conditions, where the determinant can be zero. 1. If the complete row of a matrix is zero. Example: 0 0 0 1 1 2 2 3 1 etc. 2. If any row or column of a matrix is the constant multiple of another row or column. Example: 1 2 3 2 4 4 1 2 5 etc. 3.
