Q12 of 108 Page 88

If , and A + A’ = I, if the value of a is

Given A =

Therefore, A’ =


Also given that A + A’ = I


(Putting the values in the above equation)





We know when two matrices are equal only when all their corresponding elements or entries are equal i.e. if A = B, then aij = bij for all i and j.


This implies,
