I am working on a PDE problem like this:
Consider the wave equation with homogeneous Neumann-Dirichlet boundary conditions:
(b) State the eigenvalue problem for ...
(c) ...
(d) ...
I am posting this asking for help on answering (a) since I do not have background whatsoever in either engineering or physics. I know how to work out the rest of questions after (a), since they are all math questions.
Thank you very much for your time and help.
Consider the wave equation with homogeneous Neumann-Dirichlet boundary conditions:
##\begin{align}
u_{tt} &= c^2U_{xx}, &&0<x<\mathscr l, t > 0\\
u_x(0, t) &=u(\mathscr l, t) = 0, &&t > 0\\
u(x, 0) &=f(x), &&0<x< \mathscr l\\
u_t(x, 0) &=g(x), &&0<x< \mathscr l
\end{align}##
(a) Give a physical interpretation for each line in the problem above.u_{tt} &= c^2U_{xx}, &&0<x<\mathscr l, t > 0\\
u_x(0, t) &=u(\mathscr l, t) = 0, &&t > 0\\
u(x, 0) &=f(x), &&0<x< \mathscr l\\
u_t(x, 0) &=g(x), &&0<x< \mathscr l
\end{align}##
(b) State the eigenvalue problem for ...
(c) ...
(d) ...
