What is the difference between these two terms, or are they completely synonymous? I have frequently seen either used in connection with pitch and roll.

are you sure you are in the right place for this question? Did you at all bother to google these terms and read the Wiki articles on them? –  Ittay Weiss Feb 7 '13 at 2:17
Yes, a few times, and with no luck at all. And yes, I am pretty certain there is no more relevant place to ask this general question. –  Levi Lindsey Feb 7 '13 at 21:05

There are others probably more qualified to speak on this subject than I, but from what I've gleaned from the Wikipedia pages on Azimuth and Yaw:

Azimuth seems to be used to represent an absolute heading, while yaw is a measurement of how much a craft turns from its current orientation.

Thus, if your azimuth went from $90^\circ$ to $184^\circ$, your yaw was $94^\circ$, while your current azimuth is $184^\circ$.

So yaw is merely change in azimuth? It just seems odd, considering that I know that the corresponding terms for the other axes--pitch and roll--are commonly used both to describe absolute orientation and change of orientation. –  Levi Lindsey Feb 7 '13 at 21:10
I will give a disclaimer that I could be wrong. However, upon reading those wiki articles (and from what else I've read when looking at compass sensors), I see azimuth always referring to absolute heading. Yaw I typically see referring to change in heading: google.com/… –  apnorton Feb 7 '13 at 22:33
