Question 1. (15 marks) d2 (a) Show that a is a hermitian linear transformation, with respect to the inner product L (f, g> = a [0 f(x)*g(x) dx (a e Rm, when acting on the vector space of (nice) functions satisfying f '(0) = f '(L) = 0. (2 marks) (b) Use this to explain how to justify the following eigenfunction expansion: 1 0 mrx f(x) = 5610 + gun COS T. [You need not justify the actual form of the eigenfunctions.] (2 marks)
