    Partial differential equation



    a) Write down the system of equations that models this physical problem.

    b) Think of some change of dependent variables that produces another wave equation problem with homogeneous boundary conditions. (The other equations may become inhomogeneous as a result.)

    c) Solve the equations from part (b) using the method of eigenfunction expansions.

    d) Describe what happens when f(t)= 1- cos(c&#960;t/L).
