`|[cos x,sin x],[sin x,cos x]|`

If matrix A=[[cos x,-sin x],[sin x,cos x]] then A+A'= I value of x is Where , A' represent transpose of A and x in(0,pi)

If |[0,cos x,-sin x],[sin x,0,cos x],[cos x,sin x,0]|^2 = |[1,-a,a],[-a,1,a],[a,a,1]| then a=

If A=[(cos x, sin x),(-sin x,cos x)] , then A(adj A)=

if A + A ' = I ,then find the value of x , if A = [[ cos x, − sin x],[ sin x, cos x ] ]

If F(x)=[[cos x,-sin x,0sin x,cos x,00,0,1]], then which of

If P(x)=[[cos x,sin x-sin x,cos x]] then show that P(x)P(y)=P(x+y)=P(y)P(x)

If A=[{:(cos x,-sin x),(sin x,cos x):}] ,then A+A^(-1)=I if the value of x is a. (pi)/(6) b. (pi)/(3) c. "" pi d. (3 pi)/(2)

If f (x)={:((cos x,-sin x,0),(sin x,cos x,0),(0,0,1)):},"show that "(f(x))^(-1) = f(-x) .

If F(x) =[(cos x, -sin x,0),(sin x,cos x,0),(0,0,1)] show that F(x)F(y)=F(x+y)

If F(x)=[("cos"x,-sin x,0),(sin x,cos x,0),(0,0,1)] and G(y)=[(cos y,0,sin y),(0,1,0),(-sin y,0,cos y)] , then [F(x) G(y)]^(-1) is equal to
