  1. Mar 29, 2008 #1

    2. Relevant equations
    I'm attempting to read ahead, so I can follow the lectures in linear algebra. However, this text starts the chapter with question but no solutions (I check back of text and solution manual). So I am posting here, lokking for critiques, suggestions, etc. I got through #4, but am not confident I am doing these correctly. I haven't yet figured out what they want from #5.

    3. The attempt at a solution
