   Solve the system of equations α(1 1 1) + β(3 2 1) + γ(1 1 0) + δ(1 0 0) = (a b c) for arbitrary a, b, and c. If there is always a solution, then the vectors span R3; if there is a choice of a, b, c for which the system is inconsistent, then the vectors do not span R3.

   In order to show a set is linearly independent, you start with the equation c₁x⃑₁ + c₂x⃑₂ + ... + cₙx⃑ₙ = 0⃑ (where the x vectors are all the vectors in your set) and show that the only solution is that c₁ = c₂ = ... = cₙ = 0. If you can show this, the set is linearly independent.

   Linearly independent vectors with examples. A set of vectors is linearly independent when none of the vectors can be written as a linear combination of the other vectors. This applies to vectors in \ (\mathbb {R}^n\) for any \ (n\) or vector spaces like the polynomial spaces.

   Sep 26, 2012 · If you solve this system (say, by Gaussian elimination) you will find that it has non zero solution (for example $r_1=1,r_2=-1,r_3=1,r_4=-1$) so $u_1-u_2+u_3-u_4=0$ and your vectors are linearly depented.

   Is the set u v w linearly independent?

   • Thus this means the set {→u, →v, →w} is linearly independent. In terms of spanning, a set of vectors is linearly independent if it does not contain unnecessary vectors, that is not vector is in the span of the others. Thus we put all this together in the following important theorem. Let {→u1, ⋯, →uk} be a collection of vectors in Rn.

   What are the tools of spanning linear independence and basis?

   • The tools of spanning, linear independence and basis are exactly what is needed to answer these and similar questions and are the focus of this section. The following definition is essential. Let U and W be sets of vectors in Rn. If all vectors in U are also in W, we say that U is a subset of W, denoted U ⊆ W

   Are all vectors linearly independent if they span R3?

   • So in general, and I haven't proven this to you, but I could, is that if you have exactly three vectors and they do span R3, they have to be linearly independent. If they weren't linearly independent, then one of these would be redundant. Let's say that that guy was a redundant one.

   What if the three 2-tuples were linearly independent?

   • If the three 2-tuples were linearly independent, it would mean that the a 2-tuple could not be expressed as a linear combination of the other two. But since the two are linearly independent, the third 2-tuple can be expressed with the other two, which is a contradiction.

   What if all C1 C2 C3 are linearly independent?

   • If they're linearly independent then all of these have to be-- the only solution to this equation would be c1, c2, c3. All have to be equal to 0. c1, c2, c3 all have to be equal to 0. Linear independence implies this, this implies linear independence.
