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

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

If A=[(cos theta, sin theta, 0),(-sin theta, cos theta, 0),(0,0,1)] then

The inverse of [(cos theta, -sin theta, 0),(sin theta, cos theta, 0),(0,0,1)] is

I: If the matrix A =[(8,-6,2),(-6,7,-4),(2,-4,lamda)] is singular one, then lamda=3 II: If the matrix [(cos theta, sin theta, 0),(sin theta, cos theta, 0),(0,0,1)] is singular then theta=pi//2

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

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