Homework Statement
Please see attached pdf. Can anyone please advise on how to approach the questions or provide websites where I can read up on it? I am reading Griffiths but it doesn't seem to cover this much. And I don't know how to google on this topic because I can't type the characters in.
Homework Equations
The Attempt at a Solution
For part 1a, I tried to rearrange the second equation given in the problem such that a- and a+ are isolated. I then substituted them back into the first equation. But I don't think that's what the problem is after.
For part 1b, I tried substituting the first euqation of H into the new expression with 'nu'. Am I heading in the right direction?
