21) also depends on the position of the axes. In applied work, however, one is frequently indifferent as to which particular point is selected as the origin. 21) are independent of the location of the origin. 11. A linear vector equation of the form γ1X1 + γ2X2 + ⋯ + γkXk = 0 is independent of the position of the origin if and only if γ1 + γ2 + ⋯ +γk = 0. , En. 8, where k = n = 2. 8 Two arbitrary vectors X1 and X2 in terms of translated vectors and . 22) 60 An important special case arises when γ1, = k − 1 and γ2 = γ3 = ⋯ = γk = 1, and the centroid becomes the mean vector We then have where (k − 1)−1−1−1−⋯−1 = 0, so that the mean vector is not affected by translation of axes.

24) The corresponding vector spaces are known as Minkowski spaces and are denoted by Lp. Thus for every particular value of p we obtain a different normed metric space. Three special cases are of particular interest—L1, L2, and L∞. 9), and for this reason it is at times known as the “city block” distance.
