sphericalHarmonic

The spherical harmonic $Y_l^m (\theta,\phi)$ in Math. A solution of the partial differential equation

$\frac{ 1 }{ \sin \theta } \frac{ \partial }{ \partial \theta } \left( \sin \theta \frac{ \partial f }{ \partial \theta } \right) + \frac{ 1 }{ \sin^2 \theta } \frac{ \partial^2 f }{ \partial \phi^2 } + l(l+1) f = 0$
