Question

If A, B are symmetric matrices of same order, then AB-BA?

Answer 1

Answer:

f A, B are symmetric matrices of same order, then AB − BA is a A. Skew symmetric matrix B. Symmetric matrix C. Zero matrix D. Identity matrix A and B are symmetric matrices, ∴ A' = A and B' = B Consider (AB – BA)' = (AB)' – (BA)' = B'A' – A'B' = BA − AB = − (AB – BA) ∴ (AB – BA)' = − (AB – BA)

Answer 2

a b minus b a is is symmetrical matrix
