Question

given, [8 -2 1 4]*N=[1 2 1 0]. Find: (i) order of matrix N (ii) matrix N

Answer 1

Answer:

Answer:

(a) is symmetric if

M is symmetric and skew-symmetric, if M is skew-symmetric.

(b) (MN - N M) = (.M N ) - (NM)

= NM - MN = - (MN - NM)

Skew-symmetric, when M and N are symmetric

(c)

\, \, Not correct

(d) (adj MN) =(adj N).(adj M)

. Not correct.
