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).
