But sinc...Indeed. <br />det(A) always equals det(A^T). <br />But since A is skew-symmetric, i.e., A = -A^T, we get<br />det(-A^T) = det(A^T)<br />i.e., (-1)^3 det(A^T) = det(A^T).<br /><br />It follows that A is singular and the problem is self-contradictory.Ankur Kulkarnihttps://www.blogger.com/profile/16411971742511540520noreply@blogger.com
