The dot product(adsbygoogle = window.adsbygoogle || []).push({}); A.Bis the magnitude of vectorAtimes the projection ofBontoA.

B.Ais the magnitude of vectorBtimes the projection ofAontoB.

Correct?

A.B=B.Aand this makes sense. But, say you're trying to find the components of a vectorVin the direction of a vectorW. Would it matter whether or not you wroteV.WorW.V?

EDIT: Also, does anyone know what it means (geometrically speaking) to find the components of a vector in the direction of another vector? I can give an example from a book if needed.
