Normalisation constant~ help~~ 1. The problem statement, all variables and given/known data An electron is in the spin state |> = A (3i, 4), so determine the normalisation constant A. 2. Relevant equations :uhh: 3. The attempt at a solution Well, I get confused about this questions, can anybody tell me what the normalisation constant is in this case? And does "in the spin state" mean something for given condition? Thanks a lot.
