    For vectors to belong to the set of basis 1. they should be linearly independent 2. They should span the space R3.

    Okay, would proving the determinant is non-zero be sufficient?

    That would probably prove that they are linearly independent right? you will have to show that for any point (a,b,c) in R3 (a,b,c) = k1v1+k2v2+k3v3

    Yes i see. Linear independence would be proved. After making Linear combinations would i then sub in a=0, b=0 and c=0 to see if k1=k2=k3=0?
