A unit vector is a vector with a magnitude of one unit.
Unit vectors have a magnitude of one, and the specific unit vectors i and j
represent the positive horizontal and vertical unit vectors in a two dimensional plane. We can write any two
dimensional vector in terms of these two unit vectors, and that notation is often seen in Calculus.

Unit Vector
A unit vector is a vector with a magnitude of one unit.
Any vector has an associated unit vector in the same direction but having a magnitude of one. Any vector can be
expressed as a scalar multiple
of its unit vector.
The following diagram shows how to normalize a vector or how to determine a unit vector. Scroll down the page for more examples and solutions of how to find a unit vector.
