Vector Norms - USM
www.math.usm.edudistance and convergence. Given a vector norm kk, and vectors x;y 2Rn, we de ne the distance between x and y, with respect to this norm, by kx yk. Then, we say that a sequence of n-vectors fx(k)g1 k=0 converges to a vector x if lim k!1 kx(k) xk= 0: That is, the distance between x(k) and x must approach zero. It can be shown that regardless of

Vector Calculus - Whitman College
www.whitman.eduThus, work in the vector setting is still “force times distance”, except that “times” means “dot product”. If the force varies from point to point, it is represented by a vector field F; the dis-placement vector v may also change, as an object may follow a …

This is the speed of the wind that will act as the second vector in the problem. When given directions such as “North of East ”, South of West or “North to South”you must refer to a compass.
