2. Consider the fourth-order boundary-value problem p''(x) – a*q(x) = 0 p(0) = p'(0) = P(1) = p"(1) = 0 where a > 0. Show that there is a non-trivial solution p(x) if and only if tan a = tanh a. Note: This boundary-value problem arises in modeling the vibrations of a beam that is clamped at one end and simply supported at the other. (See hint for problem 1.)
