Find the matrix representation of the ������2 operator for the spin-1 system. Do this by explicit matrix calculation and a second time by inspection of the eigenstates of the operator.

Zack notices that segment nm and segment pq are congruent in the image below: which step could him determine if δnmo ≅δpqr by sas? (5 points) segment mo ≅ segment qr segment on ≅ segment qp ∠ n ≅ ∠ r ∠ o ≅ ∠ q
