(Give your answers in terms of n, making sure that each value of n corresponds to a unique eigenvalue. Boundary Value and Eigenvalue Problems Up to now, we have seen that solutions of second order ordinary di erential equations of the form y00= f(t;y;y0)(1) exist under rather general conditions, and are unique if we specify initial values y(t 0); y0(t 0). The eigenvalues of the problem (1), (2), and (3) are the zeros of the function ∆,andif∆( 0)=0then is an eigenfunction corresponding to the eigenvalue 0 only in case = 1 0 + 2 0 Such functions can be used to repre-sent functions in Fourier series expansions.
