a subspace of Rn? Solution: Assume that W = n ~x A~x =~b o is a subspace of Rn. Then, if ~x 0 is in W, so is 2~x 0. Since ~x 0 is in W, we have that A~x 0 =~b This means that A(2~x 0) = 2A~x 0 = 2~b But for 2~x 0 to be in W, we must by de nition have A(2~x 0) = ~b. Therefore, we must have that ~b = 2~b which implies that our only possibility is ...

Remember from chapter 2 that a subspace is a speciflc subset of a general complex linear vector space. In this case, we are going to flnd relations in a subspace C3 of an inflnite dimensional Hilbert space. The idea is to flnd three 3 X 3 matrix operators that satisfy relations

A subspace V of Rnis a subset of Rnthat contains the zero element and is closed under addition and scalar multiplication: (1) 0 2V (2) u;v 2V =)u+ v 2V (3) u 2V and k2R =)ku 2V Equivalently, V is a subspace if au+bv 2V for all a;b2R and u;v 2V. (You should try to prove that this is an equivalent statement to the rst.)

if the image of T is an n-dimensional subspace of the (n-dimensional) vector space W. But the only full-dimensional subspace of a nite-dimensional vector space is itself, so this happens if and only if the image is all of W, namely, if T is surjective. In particular, we will say that a linear transformation between vector spaces V and

The formula for the orthogonal projection

The formula for the orthogonal projection

www.math.lsa.umich.edu

Let V be a subspace of Rn. To nd the matrix of the orthogonal projection onto V, the way we rst discussed, takes three steps: (1) Find a basis ~v 1, ~v 2, ..., ~v m for V. (2) Turn the basis ~v i into an orthonormal basis ~u i, using the Gram-Schmidt algorithm. (3) Your answer is P = P ~u i~uT i. Note that this is an n n matrix, we are ...

The plane Π is not a subspace of R4 as it does not pass through the origin. Let Π0 = Span(v1,v2). Then Π = Π0 +x0. Hence the distance from the point z to the plane Π is the same as the distance from the point z−x0 to the plane Π0. We shall apply the Gram-Schmidt process to vectors v1,v2,z−x0. This will yield an orthogonal system w1,w2,w3.
