The following linear combination of states is considered in almost all quantum mechanics textbooks when they try to explain the addition of spin 1/2 and orbital angular momentum. The thing I don't understand is how the left hand side is equal to the right. Please, if you can, explain how.
|j,m + 1/2> = a|lm,+> + b|lm,-> where |+> is spin up and |-> is spin down.
Thanks,
Sam
