Vectors - shortest distance

  1. Jun 10, 2008 #1
    Say you have two vectors: a and b.

    Is the shortest distance between these two vectors when a line perpendicular to a meets vector b, or when a line perpendicular to vector b meets vector a?

    Hi nokia8650! :smile:

    The length of one line is a.cosθ, and of the other is b.cosθ.

    But those are the distances between one line and the other endpoint.

    There is no such thing as the distance between two vectors … only between their endpoints.
