(algebra, geometry, mathematics, topology) A set of elements called vectors, together with some field and operations called addition (mapping two vectors to a vector) and scalar multiplication (mapping a vector and an element in the field to a vector), satisfying a list of constraints.

(linear algebra) a vector with the size given by the product of two vectors computed as the product of the magnitudes of the vectors and the sine of the angle between their directions, and directed perpendicular to the given two vectors, with positive orientation.

(mathematics) Any function whose range is n-dimensional

plural of unit vector

(mathematics) a function mapping a subset of ℝⁿ into a subset of ℝⁿ / (differential geometry) a function which associates, to each point on a surface, a vector in the tangent plane of that point

(mathematics) A vector with the length of 1.

(physics, mathematics) A vector whose direction is that of the direction of propagation of a wave, and whose magnitude is inversely proportional to its wavelength

plural of vector sum

plural of radius vector

(mathematics) A straight line (or the length of such line) connecting any point, as of a curve, with a fixed point, or pole, round which the straight line turns, and to which it serves to refer the successive points of a curve, in a system of polar coordinates.
