- 11. Find two nonzero matrices and such that.arrow_forwardLet A and B be square matrices of order n satisfying, Ax=Bx for all x in all Rn. a Find the rank and nullity of AB. b Show that matrices A and B must be identical.arrow_forwardLet A,D, and P be nn matrices satisfying AP=PD. Assume that P is nonsingular and solve this for A. Must it be true that A=D?arrow_forward
- Use an example chosen from 22 matrices to show that for nn matrices A and B,ABBA but AB=BA.arrow_forwardLet A and B be square matrices of order 4 such that |A|=4 and |B|=2. Find a |BA|, b |B2|, c |2A|, d |(AB)T|, and e |B1|.arrow_forwardFind an orthogonal matrix P such that PTAP diagonalizes the symmetric matrix A=[1331].arrow_forward
