Homework Help: Special Numbers?

  1. Apr 19, 2010 #1
    1. The problem statement, all variables and given/known data

    "Whats special about vectors a, b, and c with respect to R3"

    a= (1,2,-3)
    b= (-2,5,8)
    c= (1,3,5)

    2. Relevant equations


    3. The attempt at a solution

    N/A, I see nothing special about them.

    Vectors can span a space, so maybe your vectors span R3. How could you check this?

    Although it might be a spanning set I don't think that is the special property.
