The value of the determinant
Web12 years ago. In the process of row reducing a matrix we often multiply one row by a scalar, and, as Sal proved a few videos back, the determinant of a matrix when you multiply one row by a scalar, is the determinant of the original matrix, times the scalar. So you can clearly row reduce a matrix to the identity matrix but have a determinant ... WebIn mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It characterizes some properties of the matrix and the linear map represented by …

WebWhat is a Determinant? It is a scalar value that is obtained from the elements of the square matrix and having the certain properties of the linear transformation described by the matrix. The determinant of a matrix is positive or negative depend on whether linear transformation preserves or reverses the orientation of a vector space. WebThe determinant of the linear transformation determined by the matrix is . The free coefficient in the characteristic polynomial of the matrix is . Depending on the definition of the determinant you saw, proving each equivalence can be more or less hard. Share Cite Follow edited Apr 9, 2013 at 6:23 answered Apr 9, 2013 at 6:17 Ittay Weiss
