Linear Algebra Homework

  • Homework is normally due at 11:59pm (I won't check 'til morning).
  • Late homework will not be accepted.
  • You are encouraged to work together on these problems.
  • They may be handed in jointly (unless I change my mind).
  • Present work neatly and legibly (your grader thanks you).
  • Label each problem and page number.
  • Assemble them in correct order.
  • Scan your homework into one .pdf
  • At the top of page 1, clearly print your NAME(S).
  • An "H" means the problem must be done by hand.
  • An "H" problem may be double-checked with a computer.
  • Parentheses "( )" mean that problem is not to be handed in.
