Lecture: MWF 11:00-11:50 AM in room B402A of the AP&M building (recordings available at

Coronavirus Considerations:
Lectures will be recorded and available online, and office hours will
be available both in-person and over Zoom. So if you are feeling ill or
have been exposed to COVID19, then you are encouraged to not come to
class or office hours. Additionally, if I ever feel sick or have been
exposed, then classes will occur remotely over Zoom until it is safe
for me to return to campus.

Exams: There will be one midterm and one final exam.
- Midterm (Solutions):
In class Friday Oct. 29. Will cover all of Chapter 1 and the first
three sections of Chapter 2. In case of illness or covid exposure you
can take the exam remotely (at the same date and time) but you must
email me at least an hour in advance to let me know. Practice Midterm.
- Final Exam (Solutions):
Tuesday Dec. 7 from 11:30 AM to 2:30 PM in our normal lecture room.
Will cover everything learned in the class. In case of illness or covid
exposure you
can take the exam remotely (at the same date and time) but you must
email me at least an hour in advance to let me know. Practice Exam
Grading: Your course grade will be computed from the maximum of the following two weighted formulas:
- 30% homework + 30% midterm + 40% final
- 40% homework + 60% final
