Math Problem Statement
Solution
I see that you’ve uploaded an image from the book Linear Algebra Done Right by Sheldon Axler, specifically from the section on span and linear independence (Exercises 2A). Here are some of the questions presented in the image:
-
Find a list of four distinct vectors in whose span equals .
-
Prove or give a counterexample: If spans , then the list also spans .
-
Suppose is a list of vectors in . For , let . Show that .
-
(a) Show that a list of length one in a vector space is linearly independent if and only if the vector in the list is not 0. (b) Show that a list of length two in a vector space is linearly independent if and only if neither of the two vectors in the list is a scalar multiple of the other.
-
Find a number such that is not linearly independent in .
Would you like to focus on a particular problem from this list or go over a solution in detail?
Here are some related questions to expand the concepts:
- What are the conditions for a set of vectors to span a vector space?
- How do you check if a set of vectors is linearly independent?
- What is the geometric interpretation of spanning in ?
- How does changing a single vector in a set affect the linear independence of the set?
- Can you provide an example of a set of linearly dependent vectors in ?
Tip: To prove linear independence, remember that a set of vectors is linearly independent if and only if the only solution to the equation is .
