    How Do You Prove This Linear Transformation?

    What does the transpose of: example, [1 0 -1]? how can you transpose that? For example the L([a b c]*) --> [a + b a - c]* how do i show that this is a linear transformation? *this is transposed.

    Linearly Dependent Sets: Answers to Your Questions

    Do all linearly dependent sets have elements that are linear combinations of each other? Or does this apply only to some of the Linearly Dependent sets? And as a follow up question: How do you know if a set of 2x2 matrices is linearly dependent or linearly independent? Thank you and may...
