`|[cos theta,-sin theta,0],[sin theta,cos theta,0],[0,0,1]|=?`

Find the inverse of A=[[cos theta,-sin theta,0sin theta,cos theta,00,0,1]]

If f(theta)=[(cos theta, -sin theta,0),(sin theta, cos theta, 0),(0,0,1)] then {f(theta)^(-1)} is equal to

If the matrix [{:(cos theta,sin theta,0),(sin theta,cos theta,0),(0,0,1):}] is singular, then what is one of the values of theta ?

If A=[(cos theta,sin theta,0),(-sin theta,cos theta,0),(0,0,1)] , where A_(11), A_(12), A_(13) are co-factores of a_(11), a_(12), a_(13) respectively , then the value of a_(11)A_(11)+a_(12)A_(12)+a_(13)=

cos m theta-sin n theta=0

What is the inverse of the matrix A= ({:(cos theta, sin theta ,0),(- sin theta, cos theta,0),(0 , 0, 1):})

If the matrix ({:(cos theta, sin theta, 0),(sin theta, cos theta, 0),(0,0,1):}) is singular, then what is one of the value of theta ?

If A= [[cos theta,-sin theta],[sin theta,cos theta]] ,then Adj A is (a) [[cos theta,-sin theta],[cos theta,sin theta]] (b) [[1,0],[0,1]] (c) [[cos theta,sin theta],[-sin theta,cos theta]] (d) [[-1,0],[0,-1]]
