This issue has been discussed (argued?) at length in this very forum: http://forum.allaboutcircuits.com/showthread.php?t=15741Phasors are vectors.
I'm not sure if there was a final resolution.
In another wiki-type page: http://en.wikibooks.org/wiki/Circuit_Theory/PhasorsVectors with standard angular velocity that rotate in the cartesian plane.
All my classes confirmed that and wikipedia seems to agree: http://en.wikipedia.org/wiki/Phasor
In fact, it reads "In physics and engineering, a phase vector ("phasor") is a representation of a sine wave whose amplitude (A), phase (θ), and frequency (ω) are time-invariant."
we find this quote:
"Phasors will always be written out either with a large bold letter (as above), or will be written out with a vector notation, such as the letter \vec{V} This wikibook prefers the former notation for the simple reason that phasors are not vectors (or else presumably, we would call them "vectors")."
Actually, in EE textbooks written before, say, 1950 (they can still be found in your local university library), what we now call phasors were still given the name "vectors". The word phasor (and for a short period, sinor) hadn't yet been coined, and there was considerable discussion as to whether the concept was needed, and whether it differed from the vector concept.
