Linear Algebra and Differential Equations
Course Head: Oliver Knill
Office: SciCtr 432
  • Homework is always due the next class. There are exceptions around midterms.
  • The Tue/Thu section has the same homework.
  • Homework is due at the beginning of class. We have a strict no late HW policy. You have 3 ``jokers": this means that we will delete the least 3 HW scores at the end.
  • Collaborations and discussions with class mates, TF's and CA's are welcome, you must write down each home work on your own.
  • Checking work with a computer algebra system is allowed. 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.
