Definition of determinants 2 x 2 and generalized to n x n. Learn how to use the Cofactor Expansion across any row and down any column. Determinant of triangular matrices. | Using row operations with computing determinants. Combining cofactor expansion with row operation to compute determinants. Properties of determinants, transpose, products of matrices. If determinant of matrix is zero then the matrix is singular (i.e. no inverse). If determinant of matrix is non-zero then matrix is nonsingular (i.e. inverse of matrix exist). |
