For 3×3 matrices M and N, which of the following statement(s) is (are) NOT correct ?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(c,d)
(N T MN) T = N T M T N is symmetric if M is symmetric and skew-symmetric if M is skew-symmetric.
(MN – NM) T = (MN) T – (NM) T = NM – MN = – (MN – NM)
skew symmetric
(MN) T = N T M T = NM ≠ MN hence NOT correct
standard result is
adj(MN) = (adjN) (adj M)] ≠ (adjM) (adjN)
