Hello everyone, can anyone help me with solving Laplace’s equation inside a semi-infinite strip. Is there specific steps to follow. I'm gonna give an example and I will be really grateful if someone explains to me. Solve Laplace’s equation ∇2u = 0 inside a semi-infinite strip (0 < x < ∞, 0 < y < H) with the following boundary condi- tions: u(x,0) = 0, u(x,H) = 0, u(0,y) = f(y). I miss the classes and I feel I'm lost.
