This result is just the product of the two above - moving source causes
one shift and moving receiver causes another to get:

I do *not* recommend memorizing these equations - I don't have them
memorized myself. It is *very* easy to confuse the forms for source
and receiver, and the derivations take a few seconds and are likely
worth points in and of themselves. If you're going to memorize
anything, memorize the *derivation* (a process I call ``learning'',
as opposed to ``memorizing''). In fact, this is excellent advice for
90% of the material you learn in this course!
