Homework Help: What dimension is the vector {0,0,0} in?

  1. Nov 1, 2012 #1
    What dimension is the vector [0,0,0] in? For example, I know that vector [o] is in dimension zero, but would [0,0,0] be in that too? Or, is it classified as being in R3 since there are three components?

    It is the zero vector in ##R^3##. ##R^3## is a 3-dimensional vector space and that zero vector is one of its elements.

    No, this is a vector in R, which can be considered a vector space of dimension 1. Every vector in this space, including the zero vector, has a dimension of 1.
