Position (vector)
In geometry, a position or position vector, also known as location vector or radius vector, is a Euclidean vector which represents the position of a point P in space in relation to an arbitrary reference origin O. Usually denoted s or r, it corresponds to the displacement from O to P:
Frequently this is used in two-dimensional or three-dimensional space, but can be easily generalized to Euclidean spaces in any number of dimensions.

Famous quotes containing the word position:
“One reason—perhaps the chief—of the virility of the Roosevelts is [their] very democratic spirit. They have never felt that because they were born in a good position they could put their hands in their pockets and succeed. They have felt, rather, that being born in a good position, there is no excuse for them if they did not do their duty by the community.”
—Franklin D. Roosevelt (1882–1945)
