You'll need to transform the problem such that the new problem has these kind of BC's. One usually tries
and find and such that .
I have an exam tomorrow, and I came across one question that I don't really know how to start and I was really hoping someone could help me out with it.
Use the method of eigenfunction expansion to obtain a solution to
with initial condition:
BC's:
where are given constants.
So I need to start with a trial solution based on the homogeneous part of the problem i.e.
which if the boundary conditions were something like I would start with a solution
but I don't know how to determine a trial solution if the BC's are non-homogeneous.
