If `A=[(costheta, -sin theta ),(sin theta, cos theta) ]` , then the matrix `A^(-50)` when `theta=pi/12`, is equal to :

If A = [(costheta,-sintheta),(sintheta,costheta)] , then the matrix A^(-50) , when theta = (pi)/(12) , is equal to

If A = [(costheta,-sintheta),(sintheta,costheta)] , then the matrix A^(-50) , when theta = (pi)/(12) , is equal to

If A = [(costheta,-sintheta),(sintheta,costheta)] , then the matrix A^(-50) , when theta = (pi)/(12) , is equal to

If A = [(costheta,-sintheta),(sintheta,costheta)] , then the matrix A^(-50) , when theta = (pi)/(12) , is equal to

If A = [{:("cos" theta, -"sin"theta),("sin"theta, "cos"theta):}] , then the matrix A^(-50) " when " theta = (pi)/(12) , is equal to

If sin theta + costheta = m and sin theta - cos theta = n , then

If sin theta + costheta = m and sin theta - cos theta = n , then

If the matrix [(cos theta, sin theta, 0),(sin theta, cos theta, 0),(0,0,1)] is singular then theta=
