GRADER'S COMMENTS ON WEEK 2:
Many papers consist just of unexplained equations with almost no words.
Remember that a solution in this class is defined as "a carefully written,
complete, formal solution, comparable to a worked-out example in a
textbook." In the future, solutions that do not meet that requirement
will not get full credit even if the answer is correct.
Also, please review the other homework instructions in the course handout.
Don't use both sides of the paper; don't write too close to the edge.
Include or paraphrase enough of the problem statement so that your paper
can be read as a self-contained explanation.
