Assignments

Rules

  • All assignments should be your individual work; otherwise, points will be deducted. [Students who wish to work together on homework must request my permission to do so in advance.]
  • Because answer keys are made available after homework is turned in, late homeworks will not be accepted. In a valid emergency, your recitation instructor (or I) may make an exception.
  • Use the blank homework forms provided in lecture, or print them from my website if necessary. Your homework must be neat: your recitation instructor is a student like you and cannot take time to decipher poor handwriting.
  • Write your name at the top. Show your work if there are calculations involved. If you need an additional sheet to show your work, put your name on it and staple it at the end.
  • Answer keys are placed on file in the Engineering Library (Benedum Hall) on Monday mornings after assignments are handed in. They are on two-hour reserve so that you can take them out to be copied.
