Yes, because since W1 W 1 and W2 W 2 are both subspaces, they each contain 0 0 themselves and so by letting v1 = 0 ∈ W1 v 1 = 0 ∈ W 1 and v2 = 0 ∈ W2 v 2 = 0 ∈ W 2 we can write 0 =v1 +v2 0 = v 1 + v 2. Since 0 0 can be written in the form v1 +v2 v 1 + v 2 with v1 ∈W1 v 1 ∈ W 1 and v2 ∈W2 v 2 ∈ W 2 it follows that 0 ∈ W 0 ∈ W.

These vibrant, green leaves pack even more health benefits than many other types of greens, making them a worthy addition to any diet. ...By de nition of the additive inverse of v we know that v + ( v) = 0, so the left side of the equation equals 0 + ( ( v)). By commutativity, this equals ( ( v)) + 0. Finally, this equals ( v) by de nition of additive identity. Meanwhile, the right side of equals v by de nition of additive identity. There-fore, the equality implies ( v) = v.Derek M. If the vectors are linearly dependent (and live in R^3), then span (v1, v2, v3) = a 2D, 1D, or 0D subspace of R^3.
