**Normalisation constant~ help~~**

## Homework Statement

An electron is in the spin state |> = A (3i, 4), so determine the normalisation constant A.

## Homework Equations

:uhh:

## 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.
