Sorry, don't have any help for you here, but....

speaking of this problem, does anyone know of a good text or other resource for studying problems like these? I've heard Delta course is good, but that seems like overkill. All one really needs is a lot of practice problems, but I haven't found anything like that yet.

Any help?

Much appreciated.
