It is a textbook problem. Applied Partial Differential Equations with Fourier Series and Boundary Value Problems, 4th Edition Haberman #2.5.12 a and b.

@ystael: Thanks. The formatting of the Latex is new stuff to me. :smile: @gabba: That is the exact problem. I think the idea is to prove that u=v-w=0, and then by the min max principle, u is the only solution. As an update, the professor said there was a mistake in the book, so we could...

Homework Statement Use Divergence theorem to determine an alternate formula for \int\int u \nabla^2 u dx dy dz Then use this to prove laplaces equation \nabla^2 u = 0 is unique. u is given on the boundary.Homework Equations u \nabla^2 u = \nabla * (u \nabla u) -(\nabla u)^2 The Attempt at...

Thank you. That is where my error was at.

Thats what I get for trying to type my work in quickly. Typo fixed.

Hello all, I'm having a little trouble getting the Latex to work, so I'm hoping this won't be too hard for everyone to understand. Homework Statement I am given the second order differential equation x2*y''(x)+(2*b+1)*x*y'(x)+c*y(x) = 0 Use the transform x=ez to find the general solution...
