Hello,
I need help understanding spin 1/2 particles and writing down expressions for the amplitidues of spin up/down states as a function of time.
Any help is appreciated or links to other information.
Thanks!

That depends on what hamiltonian etc you have.. if this is a homework question, then post it in the homework forum; the full problem given and your attempt to solution.
