Background for Hyperbolic Equations
Wave Equation
As an example of a
hyperbolic partial differential equation,
we consider the
wave equation
for0 < x < aand0
< t < b,with the boundary conditions
The wave equation models the displacement u of a vibrating elastic string
with fixed ends atx=0andx=a.Although
analytic solutions to the wave equation can be obtained with Fourier series, we
use the problem as a prototype of a hyperbolic
equation.
