1.	Let A be a square matrix of order n. Statement - 1 : `abs(adj(adj A))=absA^(n-1)^2` Statement -2 : `adj(adj A)=absA^(n-2)A`A. Statement -1 is True, Statement -2 is true, Statement -2 is a correct explanation for Statement-1.B. Statement-1 is True, Statement -2 is True, Statement -2 is not a correct explanation for Statement -1.C. Statement -1 is True, Statement -2 is False.D. Statement -1 is False, Statement -2 is True.
Answer» Correct Answer - A Statement -1 is ture (see Theorem 8 on page 16.7) `:. abs(adj(adj A))=abs(absA^(n-2)A)=absA^((n-2)n)absA` `rArr abs(adj(adjA))=abs A^(n^2-2n+1)=absA^((n-1))^2`

If `A=[[cos alpha, -sin alpha] , [sin alpha, cos alpha]], B=[[cos2beta, sin 2beta] , [sin 2 beta, -cos2beta]]` where `0 lt beta lt pi/2` then prove that `BAB=A^(-1)` Also find the least positive value of `alpha` for which `BA^4B= A^(-1)`A.B.C.D.
If `A=[[cos alpha, -sin alpha] , [sin alpha, cos alpha]], B=[[cos2beta, sin 2beta] , [sin 2 beta, -cos2beta]]` where `0 lt beta lt pi/2` then prove that `BAB=A^(-1)` Also find the least positive value of `alpha` for which `BA^4B= A^(-1)`
If `A(alpha, beta)=[("cos" alpha,sin alpha,0),(-sin alpha,cos alpha,0),(0,0,e^(beta))]`, then `A(alpha, beta)^(-1)` is equal toA. `A(-alpha, -beta)`B. `A(-alpha, beta)`C. `A(alpha, -beta)`D. `A(alpha, beta)`
`{:A=[(cos^2 alpha,cosalphasinalpha),(cosalphasinalpha,sin^2alpha)]:}` `{:B=[(cos^2 beta,cosbetasinbeta),(cosbetasinbeta,sin^2beta)]:}` are two matrices such that the product AB is the null matrix, then `(alpha-beta)` is
