    nonhomogeneous neumann boundary conditions partial perp??



    I am not sure what \partial_\perp is? Is this a typo?

    Since this is a question about Neumann boundary conditions, I think you can assume that \partial_\perp u(1,\theta) means the directional derivative in the direction of the normal (so the perp symbol stands for "perpendicular to the tangent")
