WebJun 25, 2024 · Determinant of Transpose - ProofWiki Determinant of Transpose Theorem Let A = [ a] n be a square matrix of order n . Let det ( A) be the determinant of A . Let A ⊺ be the transpose of A . Then: det ( A) = det ( A ⊺) Proof Let A = [ a 11 a 12 … a 1 n a 21 a 22 ⋯ a 2 n ⋮ ⋮ ⋱ ⋮ a n 1 a n 2 ⋯ a n n] . WebAB is just a matrix so we can use the rule we developed for the transpose of the product to two matrices to get ( (AB)C)^T= (C^T) (AB)^T= (C^T) (B^T) (A^T). That is the beauty of having properties like associative. It might be hard to believe at times but math really does try to make things easy when it can. Comment.
