Homework Help: The delta function

  1. Mar 13, 2013 #1
    A string of length L are connected in x = 0 and x = L. The point x = a, 0<a<L, are a point formed weight with mass m0 attached. Formulate the mathematical problem for small transversal oscillations .

    I got it to be:

    m0*utt(a,t) = s(a,t)(ux(a+,t)-ux(a-,t))
    u(x,0) = g(x)
    ut(x,0) = h(x)

    The answer should be

    utt - c2uxx = -(m0*g/ρ)*δ(x-a)

    How can i transform it ?
