Hi i'm having a bit of trouble working out how to do this question. As i've not done Sturm-Liouville theory before and finding it hard to work it out.

The question is

y''-2y'+(1+lamda)y=0 with homogeneous bc on x=0,1

Write in S-L form

Write the orthagonality condition.

Now i'm having trouble working out how this is done could anybody be kind enough to go through the steps needed to work this out?

Thanks very much
