Homework sets 6 and 7 are combined, and due just as spring break begins. (Don't delay ...)
There are only 9 problems in this set, but they are a bit more involved, hence its counting twice as much.
We will go over the problems in quite a bit of detail in the classes leading up to the break.
UPDATE: re-posted with a few typos fixed and some useful integrals included. Same link above.
UPDATE: useful, also useful.
