Bases for Rn

  1. Nov 30, 2014 #1
    Hey everyone I just had a quick thought that was bothering me. For a set to be a basis it must be linearly independent and span the vector space. I've seen cases however of only two vectors forming a basis for R4 I don't see how two vectors could span 4 space or am I missing something.

    A set of two basis vectors couldn't possibly span R4. Are you sure that what you saw wasn't talking about a subspace of R4?
