3. Let det(A) be the determinant of matrix A (- R^(n*n) Which are correct? (A) det(A) != 0 <=> A invertible. -> wrong (B) det(A^T) = det(A) -> not sure , but right , I guess. (C) det(AB) = det(A)*det(B) -> not sure , but right , I guess. (D) A is invertible => det(A^(-1)) = det(A)^(-1) -> ... 這三小？ (E) det(cA) = c^(n-1)*det(A) -> ...... Q__Q 所以正確的到底是.....? -- 我絕對不會說這是我的無名......... http://www.wretch.cc/blog/chris750630 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 203.73.27.242
