**Spherical Harmonic Integration plz help!!!**

Hi guys,

I have a spherical harmonic integration problem that I would like to solve

[tex]\int_S Y_{nm}^*(\omega)Y_{nm}^*(\omega) d\omega[/tex]

which I re-write as follows:

[tex]= \int_S \left|Y_{nm}^*(\omega)\right|^2 d\omega [/tex]

Am I right to say that

[tex]\int_S \left|Y_{nm}^*(\omega)\right|^2 d\omega = \frac{2n+1}{4\pi}[/tex] ???

since we know that

[tex] \left|Y_{nm}^*(\omega)\right|^2 = \frac{2n+1}{4\pi}[/tex]

Thanks in advance
