Homework Statement
Determine the matrix representation of the rotation operator
[itex] R(\phi k) [/itex] using the states |+z> and |-z> as a basis. Using your matrix representation verify that [itex] R^{\dagger}R=1 [/itex]
The Attempt at a Solution
Do I need to write [itex] R| \psi> [/itex] in terms of a matrix.
If I have [itex] |\psi>=a|+z>+b|-z> [/itex]
Then do I just operate R on [itex] \psi [/itex] and then write this in terms of a matrix.
are these related to the Pauli spin matrices
