WebIf A and B are symmetric matrices, prove that AB−BA is a skew symmetric matrix. Medium Solution Verified by Toppr It is given that A and B are symmetric matrices. Therefore, we have: A=A and B=B .............. (1) Now, (AB−BA)=(AB)−(BA),[∵(A−B)=A−B] =BA−AB,[∵(AB)=BA] =BA−AB ................ [using (1) ] =−(AB−BA) ∴(AB−BA)=−(AB−BA)
