Question content area bottom

Part 1
Which of the following criteria are necessary for a set of vectors to be an orthogonal basis for
ℝ2​?
Select all that apply.
 
 
A.
The vectors must all have a length of 1.
 
B.
The vectors must span
ℝ2.
Your answer is correct.
 
C.
The vectors must form an orthogonal set.
Your answer is correct.
 
D.
The distance between any pair of distinct vectors must be constant.
Part 2
Which theorem could help prove one of these criteria from​ another?
 
 
A.
If
S=u1, ..., up
and the distance between any pair of distinct vectors is​ constant, then the vectors are evenly spaced and hence form an orthogonal set.
 
B.
If
S=u1, ..., up
and each
ui
has length​ 1, then S is an orthogonal set and hence is a basis for the subspace spanned by S.
 
C.
If
S=u1, ..., up
is an orthogonal set of nonzero vectors in
ℝn​,
then S is linearly independent and hence is a basis for the subspace spanned by S.
Your answer is correct.
 
D.
If
S=u1, ..., up
is a basis in
ℝp​,
then the members of S span
ℝp
and hence form an orthogonal set.
Part 3
What calculation shows that
u1, u2
is an orthogonal basis for
ℝ2​?
 
Since the
inner product of Bold u 1 and Bold u 2inner product of u1 and u2
 
is
00​,
the vectors
form an orthogonal set.
 
From the theorem​ above, this proves that the vectors are also
a basis for set of real numbers R squareda basis for ℝ2
 
because they are two
linearly independent vectors in set of real numbers R squared .linearly independent vectors in ℝ2.
