Using Norm of Vector

  1. Oct 13, 2006 #1
    I don't know if I'm just having a slow day or what is going on but I am being stumped by this:

    If ||v|| = 2 and ||w|| = 3 what are the largest and smallest values possible for ||v - w||. Give a geometric explanation.

    Would it be as simple as just adding the two values for the largest, and subtracting for the smallest?

    Any help would be apreciated.

    consider the direction, and it is basically the triangle inequality.

    Think about the direction of the two vectors.
