Hi coomast, 1. Yes, time is running from -\infty to \infty. Sorry I didn't make that clearer. 2. Unfortunately \phi(x=0, |t|<\tau) is unknown. This and the fact that \phi_x(x=0) is unknown for all time is what makes the problem hard. Yep, it'd be great if you could find a series solution.

Hi, I'm trying to find an analytical solution of Laplace's equation: \phi_{xx} + \phi_{tt} = 0 with the tricky boundary conditions: 1. \phi(x=0,|t|>\tau)= 0 2. \phi(x\neq0, |t|>>\tau)=0 3. \phi_{x}(x=0, |t|<\tau)=-1 4. \phi_{t}(x, |t|>>\tau)=0 I have the following ansatz(I...
