Eigenvalue problem not Sturm Liouville

Hey!!!

Knowing that:
"The eigenvalue problem  Ly=(py')'+qy, a <= x <= b is a Sturm-Liouville problem when it satisfies the boundary conditions:

,where

is the wronskian."

I have to show that the eigenvalue problem y''+λy=0, with boundary conditions y(0)=0, y'(0)=y'(1) is not a Sturm -Liouville problem.

This is what I've done so far:

Let

solutions of the eigenvalue problem y''+λy=0 , then:
u(0)=0, u'(0)=u'(1) and   v^*(0)=0, v^{*'}(0)=v^{*'}(1).

W(u(0),v^*(0))=u(0)v^{*'}(0)-u'(0)v^*(0)=0

W(u(1),v^*(1))=u(1)v^{*'}(1)-u'(1)v^*(1)=u(1) v^{*'}(0)-u'(0)v^*(1)

How can I continue? How can I show that this is not equal to

?
