If you think we missed something and that the grading is incorrect, please ask the grader for a regrade within a week of the day the homework is returned . Here’s who graded what on this assignment: • Problem 1 & 2: Tyler Smith • Problem 3 & 4: Faraz Mohammad-Mirzaei • Problem 5: Katie Panciera • Problem 6: Jonathon Lawson A few general comments: • If you didn’t do well (or didn’t do as well as you had hoped) on this assignment, please (i) look over this key, and try to understand well what you did wrong, (ii) look over the file, on the course web page, of tips for doing well in this class, (iii) make use of office hours. • Please read the problems carefully and make sure you understand what they are asking. Some people lost points because they answered the wrong question. If you have any question about what a problem is asking for, please ask about it. • Please staple your pages together and write the problems in order to make sure that we don’t miss any problems. • By showing your work, you are more likely to get partial credit.
