Consider an algebra where the vector space is ℝ3 and
the multiplication of vectors is the conventional cross product you
learned as a beginning physics student. Find the structure
constants of this algebra.
A basis of a vector space V is a maximal linearly independent
set of vectors in V . Similarly, one can view it as a minimal
spanning set of vectors in V . Prove that any set S ⊆ V spanning a
finite-dimensional vector space V contains a basis of V .
Define a subspace of a vector space V . Take the set of vectors
in Rn such that th
coordinates add up to 0. I that a subspace. What about the set
whose coordinates add
up to 1. Explain your answers.
Let ?1 ⃗ , ?2 ⃗ , ?3 ⃗ be three vectors from ℝ3 such no two
vectors are parallel, and ?3 ⃗ is not in the plane spanned by ?1 ⃗
and ?2 ⃗ . Prove that {?1 ⃗ , ?2 ⃗ , ?3 ⃗ } forms a basis for
ℝ3
In the real vector space R 3, the vectors u1
=(1,0,0) and u2=(1,2,0) are known to lie in the span W of the
vectors w1 =(3,4,2), w2=(0,1,1), w3=(2,1,1) and w4=(1,0,2). Find
wi, wj ?{w1,w2,w3,w4} such that W = span({u1,u2,wk,wl}) where
{1,2,3,4}= {i,j,k,l}.
1, In the vector space models, you can use concepts or terms as
basic vectors. Describe the advantages and disadvantages of these
two types of vectors with respect to each other.
2. Consider following two words: {precision, precise}. Shall we
cluster them together if we set-up the similarity threshold to be
0.5? Please justify your answer. (Hint: use the dice coefficient to
compute the similarity.)
