Transcribed Image Text:4. State with a brief explanation whether the following statements are true or false.
(a) The vectors (1,0) and (0, 1) span R².
(b) The vectors (2, -1), (0, 1), and (1,0) span R².
(c) The vectors (1,0) and (0, 1) are linearly independent.
(d) The vectors (2, -1), (0, 1) and (1,0) are linearly independent.
(e) A set of any two vectors in R2 is a basis for R².
(f) A set of any three vectors in R2 must be linearly dependent.
(g) R2 is a subspace of R³.
Expert Solution
Step 1
a) true
The vectors (1 ,0) and (0,1) is linearly independent.
We know that linearly independent set of n vectors in n dimensional vector space is a basis that span vector space
(1,0) ,(0,1) is basis of R2 also span R2
b)true
(2 ,-1) ,(0,1) and (1,0) span R2
(0,1) and (1,0) togather span R2
If we add extra vectors that also span R2
