give an example for TR(AB ) =TR(BA)
Hii,
maybe it help you solving your problem
AB and BA cannot be just any two matrices. They must have the same determinant, where for 2 × 2 matrices, The determinant function has the remarkable property that
det(AB) = det(A) det(B).
So we have det
(AB) = det(A) det(B)
= det(B) det(A)
= det(BA)
