    I've attempted this but the last part is a bit dodgy (to me).

     Y_l_m = \Theta_l_m \Phi_m

     L_zY_l_m = -ih\Theta_l_m\frac{d\Phi_m}{d\phi  } (those should be partial differentials but I could't be bothered to look up the latex way of writing it.)

     \frac{d\Phi_m}{d\phi} + im\Phi_m = 0

     let   \Phi_m = e^p^\phi   so   \frac{d\Phi_m}{d\phi} = pe^p^\phi

    And then I get  \Phi_m = e^-^i^m^\phi

    But it feels like my substitution part was wrong. And then I'm asked to normalise it so should there have been some constant A in front of my function if it is indeed correct?

    It's been a while since you posted and nobody's replied yet...maybe you should check out MarkedbyTeachers.com, TSR's sister site. It has the largest library of essays in the UK.

    They've got over 181,000+ coursework, essays, homeworks etc.. all written by GCSE, A Level, University and IB students across all topics. You get access either by publishing some of your own work, or paying £4.99 for a month's access. Both ways give you unlimited access to all of the essays.

    All their documents are submitted to Turnitin anti-plagiarism software, so it can't be misused, and the site's used by hundreds of thousands of UK teachers and students.

    What's more, you can take a look around the site and preview the work absolutely free. Click here to find out more...
