**2. Determine the discretization of the wave equation with Neumann boundary conditions.**

**PDE:**
\[ u_{tt} - c^2 u_{xx} = 0, \quad 0 \leq x \leq L, \, x \in \mathbb{R} \]

**IC (Initial Conditions):**
\[ u(x,0) = f(x), \quad u_t(x,0) = g(x), \quad 0 \leq x \leq L \]

**BC (Boundary Conditions):**
\[ u_x(0,t) = 0 = u_x(L,t), \quad t \in \mathbb{R} \]
