WebSep 16, 2024 · Using Definition 3.1.1, the determinant is given by det ( A) = 1 × 4 − 2 × 2 = 0 However notice that the second row is equal to 2 times the first row. Then by the discussion above following Theorem 3.2. 4 the determinant will equal 0. Until now, our focus has … WebJan 13, 2016 · det ( A) = det ( J n) det ( A J n). det ( D n) = det ( J n) det ( D n J n) = det ( J n) a n ( x − a 1) ⋯ ( x − a n − 1). So the only difference is that we need to know det ( J n). Because J n is a permutation matrix, corresponding to σ n ∈ S n with σ ( i) = n + 1 − i, we have det ( J n) = s g n ( σ n). Notice that.
