1. The problem statement, all variables and given/known data

My homework has a Sturm-Louiville eigenvalue problem

Lu = u'' - u = 0, x ε (0,1)

with u(0)=u(∏)=0. The only solution is u(x) = 0, x ε [0,1]. Right? But then other parts of this particular problem become trivial.

2. Relevant equations

Nothing really

3. The attempt at a solution

Plugged it into Wolfram Alpha to get u(x)=0, solved it using the characteristic equation to get u(x)=0, and also did the eigenfunction expansion to get the same answer.
