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

Simplify, costheta[[cos theta, sin theta],[-sin theta, cos theta]] + sin theta [[sin theta, -cos theta],[cos theta, sin theta]]

Simplify: cos theta[[cos theta , sin theta],[-sin theta , cos theta]]+sin theta[[sin theta, -cos theta],[cos theta ,sin theta]] .

cos theta-cos3 theta+cos5 theta-cos7 theta=4sin theta sin4 theta cos2 theta

(cos theta)/(1-sin theta)=(1+cos theta+sin theta)/(1+cos theta-sin theta)

Prove the orthogonal matrices of order two are of the form [(cos theta,-sin theta),(sin theta,cos theta)] or [(cos theta,sin theta),(sin theta,-cos theta)]
