Get the free "The Span of 2 Vectors" widget for your website, blog, Wordpress, Blogger, or iGoogle. I know that their first components are zero, that is, ${\bf v} = (0, v_2, v_3)$ and ${\bf w} = (0, w_2, w_3)$. Math is a subject that can be difficult for some people to grasp, but with a little practice, it can be easy to master. Can you write oxidation states with negative Roman numerals? Is $k{\bf v} \in I$? I think I understand it now based on the way you explained it. Subspace. The set W of vectors of the form W = {(x, y, z) | x + y + z = 0} is a subspace of R3 because 1) It is a subset of R3 = {(x, y, z)} 2) The vector (0, 0, 0) is in W since 0 + 0 + 0 = 0 3) Let u = (x1, y1, z1) and v = (x2, y2, z2) be vectors in W.
