Help understanding a vibrating string question

  1. Jan 18, 2017 #1
    1. The problem statement, all variables and given/known data
    So I don't really understand what the professor means by "show why the displacements y(x,t) should satisfy this boundary value problem" in problem 1. Doesn't that basically boil down to deriving the wave equation? At least in problem 2 he says what he wants us to show.

    2. Relevant equations
    utt = c2uxx

    3. The attempt at a solution
    The problem set is in the attachment

    I would interpret that problem to mean
    1) develop the equation of motion for the system, ending up with the wave equation
    2) show that, for this situation, the boundary conditions are those suggested in the problem statement.
    In the process, you will need to show how c is related to the given information, so don't just write "c" but put it in terms of the given data.
