[[File:lighterstill.jpg]][[File:Direction.jpg|right|frame]]
==Origin==
Latin ''dīrectiōn-em'' , n. of [[action]] from ''dīrig-ĕre'' to direct
*[http://en.wikipedia.org/wiki/15th_century 15th Century]
==Definitions==
*1: [[guidance]] or supervision of [[action]] or conduct : [[management]]
*2. archaic : superscription
*3a : an explicit instruction : order
:b : [[assistance]] in pointing out the proper route —usually used in plural <asked for directions to the beach>
*4: the line or [[course]] on which something is moving or is aimed to move or along which something is pointing or facing
*5. archaic : directorate
*6a : a [[channel]] or direct [[course]] of [[thought]] or [[action]]
:b : [[tendency]], trend
:c : a guiding, governing, or [[motivating]] [[purpose]]
*7a : the [[art]] and [[technique]] of directing an [[orchestra]], band, or a show (as for stage or screen)
:b : a [[word]], [[phrase]], or sign indicating the appropriate tempo, [[mood]], or [[intensity]] of a passage or movement in [[music]]
==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.
