To restate: Closest vector and distance. Let W be a subspace of R n and let x be a vector in R n. The orthogonal projection x W is the closest vector to x in W. The distance from x to W is B x ...
Web3. Let u = i 2j, v = 2i+ 3j, and w = i+ j. Write u = u 1 + u 2, where u 1 is parallel to v and u 2 is parallel to w. Solution. Since u 1 is parallel to v and u 2 is parallel to w, we have u 1 = av and u 2 = bw; for some numbers aand b. Thus, u = av + bw; WebWe can rewrite this as being equal to x dot v, over the length of v squared, all of that times v. Wouldn't it be nice if the length of v was 1. The length of v was equal to 1. If the length of v was 1, or this is another way of saying that, v is a unit vector. Our formula for our projection would just simplify to x dot v.

So it’s a direct sum. In our example, since U ⊕ T = R3, we can write any vector v in R3uniquely as v = u+t, with u ∈ U and t ∈ T.
