Question

I'm trying to answer this question but I'm stuck. also I'm not sure if it makes sense do:

Plm(-cos theta) = (-1)^(l+m)Plm(cos theta)

specifically the ^(l+m) 

thanks!

Show that for the hydrogenic orbitals,
Înem (r, 0,0) = (-1) Vnem (r, 0, 0).
That is, nem is an eigenstate of the parity operator, with eigenvalue
(-1). Note: This result actually applies to the stationary states of any
central potential V (r) = V (r). For a central potential, the eigenstates
may be written in the separable form Rnt (r) Y (0, 0) where only the
radial function Rwhich plays no role in determining the parity of the
state-depends on the specific functional form of V (r).
