(Laplace's equation) Show that for a solution w(x, y) of Laplace's equation \,2U- = 0 in

Chapter 10, Problem 10.1.78

(choose chapter or problem)

Show that for a solution w(x, y) of Laplace's equation \(\nabla^{2} w=0\) in a region R with boundary curve C and outer unit normal vector \(\mathbf{n}\),

(10)         \(\iint_{R}\left[\left(\frac{\partial w}{\partial x}\right)^{2}+\left(\frac{\partial w}{\partial y}\right)^{2}\right] d x d y\)

\(=\oint_{C} w \frac{\partial w}{\partial n} d s\)

Text Transcription:

nabla^2 w = 0

n

iint_R[(partial w / partial x)^2 + (partial w / partial y)^2] dx dy

= oint_C w partial w / partial n ds
