Web1 Example: Method of images for Robin BC in an interval 1 1 Example: Method of images for Robin BC in an interval Here we show how to use the method of images to obtain the Green’s function for the initial value problem for the heat equation, in an interval with homogeneous boundary conditions (Robin on the left, and Dirichlet on the right). WebSolve the wave equation with Robin boundary conditions under the assumption that a 0 + a l < − a 0 a l l holds. I know that this condition means there is one negative eigenvalue λ 0 and the rest are positive. I should be able to compute λ 0 from tanh ( λ 0 l) = − ( a 0 + a l) λ 0 λ 0 + a 0 a l and the corresponding eigenfunction from http://www.multiphysics.us/BC.html bright vision glass
