Cartesian space | Euclidean n-space

Euclidean space of dimension n is the space of all n-tuples of real numbers which generalizes the two-dimensional plane and three-dimensional space.

Euclidean n-space, sometimes called Cartesian space or simply n-space, is the space of all n-tuples of real numbers, (x_1, x_2, ..., x_n). Such n-tuples are sometimes called points, although other nomenclature may be used (see below). The totality of n-space is commonly denoted R^n, although older literature uses the symbol E^n (or actually, its non-doublestruck variant E^n; O'Neill 1966, p. 3).
