Evaluate:

[tex]

\int\int \phi \nabla(\frac{1}{R}) - \frac{1}{R}\nabla\phi * \vec{n} dS

[/tex]

a) over the surface of the ellipsoid

[tex]1/9\,{x}^{2}+1/16\,{y}^{2}+1/25\,{z}^{2}=1

>

[/tex]

where

[tex]

\phi={x}^{2}+{y}^{2}-2\,{z}^{2}+4

[/tex]

2. Relevant equations

3. The attempt at a solution

We are supposed to use one greens formulas for this, but I have no clue how to even approach this one. The formulas aren't stated anywhere clearly because the section is just one long proof. If anyone could please help me get started on this I would appreciate it greatly.
