# Vector

(1) In vector algebra, a vector mathematical entity that has both magnitude (which can be zero) and direction. (2) In topology, a vector is an element of a vector space.

Vector is a high school-level concept that would be first encountered in a pre-calculus course covering vectors. It is listed in the California State Standards for Linear Algebra.

### Examples

Normal Vector: | A normal vector is a vector perpendicular to a surface. |

Tangent Vector: | A tangent vector is a vector pointing in the direction of the tangent line to the graph of a function. |
