Final answer:
To determine the solutions to the given boundary value problem, we can use the boundary conditions and the general forms of the solutions to find the unique solution.
Step-by-step explanation:
To determine the solutions to the given boundary value problem, y'' + 6y' + 34y = 0, with boundary conditions y'(0) = 0 and y'(π) = 0, we can solve for the unknown constants in the general forms of the solutions in regions I and III. Since the walls are rigid and impenetrable, the solution must vanish at the walls, so y(0) = 0 and y(π) = 0. By substituting these conditions into the general forms of the solutions, we can find the unique solution to the boundary value problem.
