Vector notation

In <a href="/facts/Mathematics/pxTouaz4">mathematics</a> and <a href="/facts/Physics/a7aH2y08">physics</a>, vector notation is a commonly used <a href="/facts/Mathematical_notation/vHgEE8cE">notation</a> for representing <a href="/facts/Vector_(mathematics_and_physics)/U8mM7A5F">vectors</a>, which may be <a href="/facts/Euclidean_vector/bCLrdksy">Euclidean vectors</a>, or more generally, <a href="/facts/Element_(mathematics)/Q2mx1vHL">members</a> of a <a href="/facts/Vector_space/M1pxMLx2">vector space</a>.
For denoting a vector, the common <a href="/facts/Typography/byx4sANl">typographic convention</a> is lower case, upright boldface type, as in v. The <a href="/facts/International_Organization_for_Standardization/IacYR7Yg">International Organization for Standardization</a> (ISO) recommends either bold italic serif, as in v, or non-bold italic serif accented by a right arrow, as in 
 
 
 
 
 
 
 v
 →
 
 
 
 
 
 {\displaystyle {\vec {v}}}
 
.
In advanced mathematics, vectors are often represented in a simple italic type, like any <a href="/facts/Variable_(mathematics)/VbQlrvKz">variable</a>.
Vector representations include Cartesian, polar, cylindrical, and spherical coordinates.
