This isn't exactly a part of any problem, but a part of a generic principle. I don't understand the use of raising and lowering operators.
[tex]L_{^+_-}=\hbar e^{^+_- i l \phi}({^+_-}\frac{\partial}{\partial \theta}+ i cot \theta \frac{\partial}{\partial \phi})[/tex]
So how does one use [tex]L_{^+_-}Y_l^m[/tex] to gain [tex]Y_l^{m{^+_-}1}[/tex]
