Here's the question you clicked on:
math_proof
is this a spanning set {(1,0,0)^t, (0,1,1)^t,(1,0,1)^t, (1,2,3)^t)
Soanning what? Did you check for linear independence? That will solve it.
spanning set for R^3
@tkhunny can you help me out
what does linear independence have to do with it? I check it comes to being dependent
If one is dependent, that's fine. How about two? Can EVERY vector in R^3 be created by these basis vectors? This is the question.
