`|(0,cosx,-sinx),(sinx ,0,cosx),(cosx, sinx ,0)|^2=|(1,-a,a),(-a,1,a),(a,a,1)|` then a =

If sin2x=1 , then |(0,cosx,-sinx),(sinx,0,cosx),(cosx,sinx,0)| equals :

cosx{(cosx)/(1-sinx)+(1-sinx)/(cosx)}, is

cosx{(cosx)/(1-sinx)+(1-sinx)/(cosx)}, is

If F(x)=[(cosx,-sinx,0),(sinx,cosx,0),(0,0,1)] and G(x)=[(cosx,0,sinx),(0,1,0),(-sinx,0,cosx)] then [F(x)G(x)]^(-1) =

Solve (sinx)/(1+cosx)+(1+cosx)/(sinx)

If Delta(x)=|(1,cosx,1-cosx),(1+sinx,cosx,1+sinx-cosx),(sinx, sinx ,1)| then int_0^(pi//2)Delta(x) dx is equal to :

If A=[(cosx,sinx),(-sinx,cosx)] and A.(adjA)=k[(1,0),(0,1)] then the value of k is

If A = ((cosx,sinx),(-sinx, cosx)) and A (adj A) = lambda ((1,0),(0,1)) then lambda is

If A=[(cosx,sinx),(-sinx,cosx)] and A.(adjA)=k[(1,0),(0,1)] then the value of k is
