(i) |(cos theta,-sin theta),(sin theta,cos theta)|

A = [(cos theta,-sin theta),(-sin theta,-cos theta)] then find A^(-1) .

If A=[{:(cos theta,sin theta),(-sin theta,cos theta):}] , then what is A^(3) equal to ?

If A=[(cos theta, sin theta),(-sin theta, cos theta)] , then prove that A^n=[[cosntheta,sin ntheta],[-sin ntheta,cos ntheta]], n in N

If I= [{:(,1,0),(,0,1):}], J=[{:(,0,1),(,-1,0):}]and B=[{:(,cos theta,sin theta),(,-sin theta,cos theta)]:}"then B"=

Let A=[(cos theta, -sin theta),(- sin theta,-cos theta)] then the inverse of a is

If A(theta) = [(cos theta,sin theta),(-sin theta,cos theta)] then prove that A^(2)(theta) = A(2 theta)

If A = [{:(cos theta,sin theta),(-sin theta,cos theta):}] then what is A^(3) equal to ?
