Question 1.
Define linear dependence.
Show hintHide hint
Think of whether one vector can be formed with the others.
Question 2.
What is linear independence?
Show hintHide hint
Remember, the scalars must all be zero.
3Question 3.
What defines linear dependence?
- A vector can stand alone.
- One vector can be expressed as a combination of others.
- All vectors are independent.
Show hintHide hint
Think about how vectors relate to each other.
4Question 4.
True or False: The vector set { (1, 2), (2, 4) } is linearly independent.
- True
- False
Show hintHide hint
Check if one vector can be made by combining others.
Question 5.
Consider the vectors v1 = (1, 2, 3), v2 = (2, 4, 6), and v3 = (3, 6, 9). Are these vectors linearly dependent or independent? Justify your answer.
Show hintHide hint
Look for constants that can express one vector through another.
Question 6.
An engineer decides to remove redundant structural supports based on vector analysis. If the original supports were based on vectors that are dependent, how would this affect the safety of the structure?
Show hintHide hint
Re-evaluate the role each support plays in load-bearing.
