==Description==

==Description==

'''Direction''' is the [[information]] contained in the [[relative]] position of one [[point]] with respect to another point without the distance [[information]]. Directions may be either [[relative]] to some indicated [[reference]] (the violins in a full [[orchestra]] are typically seated to the left of the conductor), or [[absolute]] according to some previously agreed upon [[frame of reference]] (New York City lies due west of Madrid). Direction is often indicated manually by an extended index finger or [[written]] as an arrow. On a vertically oriented sign representing a [[horizontal]] [[plane]], such as a road sign, "forward" is usually indicated by an upward arrow. [[Mathematically]], direction may be [[uniquely]] specified by a [http://en.wikipedia.org/wiki/Unit_vector unit vector] in a given basis, or equivalently by the angles made by the most direct path with respect to a specified set of axes.
