How to Proove that L+ = L1 + iL2

  1. Jul 31, 2015 #1
    1. The problem statement, all variables and given/known data
    Hello All,

    The professor asked us to prove that L+ = L1 + iL2,

    Please Help!, I have no Idea how to proceed,

    Any insight will be highly appreciated.

    2. Relevant equations
    L+ = L1+iL2=~he^iφ (∂/∂θ + i cotθ ∂/∂φ)

    3. The attempt at a solution


    L+ = L1+iL2=~he^iφ (∂/∂θ + i cotθ ∂/∂φ)
    .

    On Physics Forums it is mandatory to provide your attempted solution when posting in the homework forums.

    What have you tried? How do you interpret the question? (I.e., what do you think the question is asking of you and what are your thoughts about doing that?)
