Vector notation

Points in the polar coordinate system with pole O and polar axis L. In green, the point with radial coordinate 3 and angular coordinate 60 degrees, or (3,60°). In blue, the point (4,210°).

A cylindrical coordinate system with origin O, polar axis A, and longitudinal axis L. The dot is the point with radial distance ρ = 4, angular coordinate φ = 130°, and height z = 4.

Vector notation, commonly used mathematical notation for working with mathematical vectors, which may be geometric vectors or abstract members of vector spaces.

For representing a vector, the common typographic convention is upright boldface type, as in $\mathbf{v}$ for a vector named ‘v’. The International Organization for Standardization (ISO) recommends either bold italic serif, as in v or a, or non-bold italic serif accented by a horizontal right arrow, as in $\vec{v}$ or $\vec{a}$ . This arrow notation for vectors is commonly used in handwriting, where boldface is impractical. The arrow represents right-pointing arrow notation or harpoons. Shorthand notations include tildes and straight lines placed above or below the name of a vector.
