Solutions to Problem 3.1
In this session we compute the expectation value of the Spin of a spin-1/2 particle (like a silver atom) in a totally general direction. It's a good exercise to make sure you really understand Spin, the Pauli matrices and all this BraKet vector stuff for sure.
The problems can be found here (scroll to the bottom).
