A vector point function is a function that maps points in a domain to vectors in a vector space. Each point is associated with a vector, serving as an output of the function. This can be used to represent physical quantities like force or velocity that have both magnitude and direction.

The derivative with respect to a vector of a function is a vector of partial derivatives of the function with respect to each component of the vector.
The tail of a vector represents the starting point or origin of the vector. It is the point from which the vector extends in a particular direction.
The derivative of a function with respect to a vector is a matrix of partial derivatives.
The beginning point of a vector is referred to as its origin or initial point. It is the starting position from which the vector is measured or represented by an arrow.
In mathematics, a vector is a quantity that has both magnitude and direction. When discussing the location of a point in space, a vector can be used to describe the displacement from an origin point to that location. Therefore, the location of a point and its vector are related in terms of specifying both where the point is and in what direction it is positioned from a reference point.
