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

|[cosx,-sinx],[sinx,cosx]|

If A=[(cosx,sinx),(sinx,-cosx)] and A("adj "A)=lamda[(1,0),(0,1)] , then lamda is equal to

If A=[(cosx,-sinx),(sinx,cosx)] , then A A^(T) is

If A=f(x)=[(cosx, sinx, 0),(-sinx, cosx,0),(0,0,1)], then the value of A^-1= (A) f(x) (B) -f(x) (C) f(-x) (D) -f(-x)

If A=[{:(cosx,sinx,0),(-sinx,cosx,0),(0,0,1):}] =f(x), then A^(-1) is equal to

If (sinx)/(1+cosx)+(sinx)/(1-cosx)=4 and 0^@ le x le 90^@ , then the value of x is

If f(x) = |{:(sinx,cosx,sinx),(cosx,-sinx,cosx),(x,1,1):}| find the value of 2(f'(o))+{f'(1)}^(2)

int(1+sinx)/(sinx(1+cosx))dx

If A=[(2,0,0),(0,cos,sinx),(0,-sinx,cosx)] then (AdjA)^-1= (A) 1/2A (B) A (C) 2A (D) 4A

If (sinx)/(1+cosx)+(sinx)/(1-cosx)=4,and0^(@)ltxlt90^(@) , then find the value of x .
