DIRECTION

Direction

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, or absolute according to some previously agreed upon frame of reference . 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 unit vector, or equivalently by the angles made by the most direct path with respect to a specified set of axes.
