Linear Algebra and Differential Equations
Course Head: Oliver Knill
Office: SciCtr 432
  • Homework is always due the next class. Exceptions happen around midterms.
  • The Tue/Thu section has the same homework but split at a different place.
  • Homework is due at the beginning of class. We have a strict no late HW policy. You have 3 jokers: this means that we delete the least 3 HW scores.
  • Collaborations and discussions with class mates, TFs and CS's are welcome however, you must write down each home work on your own.
  • Checking work with a computer algebra system is alowed. We encourage exclusively to work on paper as during exams, no electronic tools are available and writing things down enhances the learning process. If you use help from a computer algebra system for the computation, acknowledge that in the paper.
  • Use words to explain your work, if necessary. Show your work. Give details of your work. Unless stated, answers only will be given no credit.
  • Homework is graded on a 10 points scale. There are 5 problems per day, 50 points maximal per day and 150 points maximal a week.
Homework rule: We have a strict no late homework policy. Homework is due in class. In case of illness (bring documentation from the Harvard University health service) we will average with less HW sets in this case. In case of non-documented illness, or forgotten homework, a jokers is invoked. Please do not ask for homework extension.
