|[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 A= [[cos x, sin x],[-sin x, cos x]] and A(adj A)=k[[1,0],[0,1]] then the value of k is

find the value for x F(x)=|[cos x,-sin x,0],[sin x,cos x,0],[0,0,1]|

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 A= [[cos x,sin x,0],[-sin x,cos x,0],[0,0,1]]=f(x) then A^-1=

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

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