We want to solve

[math]\displaystyle{ \phi(x) = \int_{-L}^{L}G(x,\xi) \left( \alpha\phi(\xi) - w(\xi) \right)d \xi }[/math]

where [math]\displaystyle{ G(x,\xi)\lt \math\gt is the [[Free-Surface Green Function]] for two-dimensional waves, with singularity at the water surface. We break the surface into \lt math\gt N }[/math] evenly spaced point [math]\displaystyle{ x_n = -L = hn }[/math] where [math]\displaystyle{ h=2L/N }[/math] and [math]\displaystyle{ n=0,1,\dots,N }[/math]
