Introduction to Vectors In order to represent physical quantities such as position and momentum in more than one dimension, we must introduce new mathematical objects called vectors. A vector is defined as an element of a vector space, but since we will only be dealing with very special types of vector spaces (namely, two- and three-dimensional Euclidean space) we can be more specific. For our purposes, a vector is either an ordered pair or triplet of numbers.

Unformatted text preview: On a two-dimensional plane, for instance, any point (a, b) is a vector. Graphically, we often represent such a vector by drawing an arrow from the origin to the point, with the tip of the arrow resting at the point. The situation for three-dimensional vectors is very much the same, with an ordered triplet (a, b, c) being represented by an arrow from the origin to the corresponding point in three-dimensional space. The vector (a, b) in the Euclidean plane....
