What is wrong here? (A differential equation)
My homework has a Sturm-Louiville eigenvalue problem
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.
Nothing really
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.
