Consider the system AX=B ,where A=[[1,1,-1],[2,1,1],[3,2,2]] , X=[[x],[y],[z]],B=[[-1],[2],[3]] , Value of tr (XB^(TT)) is (where tr(A) denotes trace of matrix A ) (a) 0, (b) 1, (c) 2, (d) 3

Which of the following about the trace of a matrix is false? (1) tr (ABC)=tr(BCA) != tr(ACB)= tr(BAC) = tr(CBA) (2) tr(AB) = tr(BA) (3) tr(A-B) = trA - trB (4) tr(A^2)= (trA)^2

If A=[(3,-4),(1,-1)] then find tr. (A^(2012)) .

If A=[(3,-4),(1,-1)] then find tr. (A^(2012)) .

If A=[(3,-4),(1,-1)] then find tr. (A^(2012)) .

If A=[(3,-4),(1,-1)] then find tr. (A^(2012)) .

Let three matrices A=[(2 ,1),( 4, 1)]; B=[(3, 4),( 2, 3)] and C=[(3,-4),(-2,3)], then tr(A) + tr((ABC)/2) + tr((A(BC)^2)/4) + tr((A(BC)^3)/8) + ......∞ (a)6 (b) 9 (c) 12 (d) None of these
