Homework Statement
X''+[tex]\lambda[/tex]*X=0 0<x<2pi
X(0)=X(2pi) and X'(0)=X'(2pi)
Homework Equations
The Attempt at a Solution
My only problem is the case when [tex]\lambda[/tex]=0
in such case the general solution is X(x)= C1+C2*x
Now, after applying the BCs, this is what I get:
C1=C2*2pi
and
C2=C2
now, what should C2 be ? zero or any value ?
if C2 is zero, we have the trivial solution only. However, if C2 is any number, we have a nontrivial solution.
how can I solve this question?
Thanks.
