Unit vector - Wikipedia, the free encyclopedia
In mathematics, a unit vector in a normed vector space is a vector (often a spatial vector) whose length is 1 (the unit length). A unit vector is often denoted by a lowercase letter with a superscri...

For example, the vector v = (1, 3) is not a unit vector because . The notation represents the norm, or magnitude, of vector v. But the vector w = is a unit vector because . ... Write vector v = (1, -3, 4) as a combination of the basic vectors i, j and k. What is a unit vector which has the same direction as v?

A   unit vector is a vector with magnitude one. We may easily convert any vector into a unit vector simply by dividing each component by the magnitude of the vector. For example, to make a unit vector, , pointing in the direction of the vector , use the formula ;

A unit vector is a vector that has a magnitude of exactly 1, and points in a particular direction. The use of unit vectors allows for a neater and easier way of setting out vector math problems. The unit vectors pointing along the positive x and y axes are labelled repectively . . .

We can define a unit vector in the x-direction by or it is sometimes denoted by . Similarly in the y-direction we use or sometimes . Any two-dimensional vector can now be represented by employing multiples of the unit vectors, and , as illustrated in Panel 8.

Classification of unit-vector fields in convex polyhedra with tangent boundary conditions ... A unit-vector field n on a convex three-dimensional polyhedron is tangent if, on the faces of , n is tangent to the faces. A homotopy classification of tangent unit-vector fields continuous away from the vertices of is given.
