The Determinant of a Matrix - Texas A&M University

Jan 20, 2009 · The determinant of transposed matrix is the same as the determinant of the original matrix: Det(AT) = Det(A). If we apply the column expansion of equation [44] to an upper triangular matrix, A, we find that Det A = a11A11, since the a11 term is the only term in the first column. We can apply equation [44] repeatedly to the cofactors. ................
