Given two vectors u,v ∈ V with v = 0 we can uniquely decompose u as a piece parallel to v and a piece orthogonal to v This is also called the orthogonal decompositionMore precisely u = u1 u2 so that u1 = av and u2⊥v Namely write u2 = u− u1 = u− avForu2 to be orthogonal to v we need 0= u−av,v = u,v− a v 2 Solving for a yields a.

MATH 240 Vector Spaces Definition A vector space is a set V on which two operations and · are defined, called vector addition and scalar multiplication The operation (vector addition) must satisfy the following conditions Closure If u and v are any vectors in V, then the sum u v belongs to V (1) Commutative law For all vectors u and v in V, u v = v u. Why or why not?. (~u ~v) w~= (~v w~) ~u= (w~ ~u) ~v Proof In fact all three numbers have the same absolute value, namely the volume of the parallelepiped with sides ~u, ~vand w~ On the other hand, if ~u, ~v, and w~is a righthanded set, then so is ~v, w~and ~uand viceversa, so all three numbers have the same sign as well Lemma 313 Let ~vand w~be two.

Thus v ( v) = v u Hence u = v (by 1 above) 5 If V and W are both subspaces of a vector space U, then the intersection of V and W (denoted by V \W) is also a subspace of U We apply the "subspace criterion" to V \W 1 0 U 2V and 0 U 2W, since V and W are subspaces of U Hence 0.

C To determine if {u, v, w, z} is linearly dependent, is it wise to check if, say w is a linear.

To S is the set of vectors in V orthogonal to all vectors in SThe orthogonal complement to the vector 2 4 1 2 3 3 5 in R3 is the set of all 2 4 x y z 3 5 such that x2x3z = 0, i e a plane The set S?. Vectors in R n Definition and Properties We assume that you are already familiar with vectors in R 2 and R 3, so that you will see that the definition extends naturally A vector in R n is a n x 1 matrix The set of all vectors in R n is called nspace We define the sum and difference of two vectors and the product of a scalar and a vector by just realizing that vectors are matrices.

For each vector u 2 V, the norm (also called the length) of u is deflned as the number kuk= p hu;ui If kuk = 1, we call u a unit vector and u is said to be normalized For any nonzero vector v 2 V, we have the unit vector v^ = 1 kvk v This process is called normalizing v Let B = u1;u2;;un be a basis of an ndimensional inner product space VFor vectors u;v 2 V, write. 6 Let u= 2 v= 1 ,w 5 ,and z= 7 Are the sets (u, v), {u, w}, {u, z), {v, w}, {v, z), and (w, z) each linearly independent?.

Thus dim(U ∩W) = dimU dimW − dim(U W) = 35−8 = 0 Since U ∩W is a 0dimensional subspace of R8, it must be {0} 14 Suppose U and W are 5dimensional subspaces of R9 with U ∩ W = {0} Then dimU ∩W = 0, and hence dim(U W) = dimU dimW −dim(U ∩W) = 10 Since U W must also be a subspace of R9, it must have dimension ≤ 9. To check that uv = v u (axiom 3) for W because this holds for all vectors in V and consequently holds for all vectors in W Likewise, axioms 4, 7, 8, 9 and 10 are inherited by W from V Thus to show that W is a subspace of a vector space V (and hence that W is a vector space), only axioms 1, 2, 5 and 6 need to be verified The.

Recall that if B = {b1,,b n} is a basis for V and v = P x ib i then we write vB for the column vector vB = x1 x n Definition 12 If f is a bilinear form on V and B = {b1,,b n} is a basis for V then we define the matrix of f with respect to B by.

Chapter 6 The Vector Product 61 Parallel vectors Suppose that u and v are nonzero vectors We say that u and v are parallel, and write u k v, if u is a scalar multiple of v (which will also force v to be a scalar multiple of u). Definition If V is a vector space over a field K and if W is a subset of V, then W is a linear subspace of V if under the operations of V, W is a vector space over KEquivalently, a nonempty subset W is a subspace of V if, whenever w 1, w 2 are elements of W and α, β are elements of K, it follows that αw 1 βw 2 is in W As a corollary, all vector spaces are equipped with at least two.

Proof This can be seen by expanding B(v w, v w) If the characteristic of K is not 2 then the converse is also true every skewsymmetric form is alternating If, however, char(K) = 2 then a skewsymmetric form is the same as a symmetric form and there exist symmetric/skewsymmetric forms that are not alternating.
