Input Form





SphericalHarmonicY[n, m, \[CurlyTheta], \[CurlyPhi]] == ((-1)^m Sqrt[(2 n + 1)/(4 Pi (n + m)! (n - m)!)] (E^(I m \[CurlyPhi])/2^n) (Cos[\[CurlyTheta]/2]^2)^(m/2) Tan[\[CurlyTheta]/2]^m D[(z + 1)^(n + m) (z - 1)^(n - m), {z, n}])/ ((Cot[\[CurlyTheta]/2]^2)^(m/2) (Sin[\[CurlyTheta]/2]^2)^(m/2)) /; z == Cos[\[CurlyTheta]]
