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

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

If sin theta+cos theta=1, then sin theta cos theta is equal to :

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

If R(theta) = [(cos theta, sin theta),(sin theta, -cos theta)] Write:- R(pi/2) .

Inverse of the matrix A=[[cos2theta, -sin2theta], [sin2theta, cos2theta]] is

If cos theta-sin theta=sqrt(2)sin theta then cos theta+sin theta is equal to

If cos2theta=0 , then |(0,costheta,sin theta),(cos theta, sin theta, 0),(sin theta, 0, cos theta)|^(2) is equal to…………
