Let X3 = X1 in axiom 2. Then so that d(X1, X2) ≥ d(X1, X1) = 0, 63 from axiom 3. A vector space for which a distance function d(X1, X2) is defined is known as a metric space. A linear vector space on which a norm is defined also becomes a metric space if we define d(X1, X2) = n(X1 − X2). A linear vector space that is a metric space in this way is known as a normed linear vector space. Note that a vector space can be a metric space without being a normed vector space since the norm provides one of the many ways in which the axioms can be satisfied.
