CLASSROOM CONDUCT EXPECTATIONS

Lecture attendance is mandatory. Office hour attendance is strongly encouraged.

Conversations: Please avoid having private conversations with your classmates during lecture and office hours.

E-mail etiquette: I will not discuss mathematics (e.g. solutions or hints of solutions to HW problems) via email. Office hours and lectures are the best venue for that purpose. However, if you have any type of administrative questions regarding this class, please do not hesitate to send me short and to the point email messages.

IMPORTANT LINKS Schedule and Homework.

GETTING HELP

Help with mathematical problems:

Section: Ask questions in section --- this is one of the main reasons why sections exist.
Office Hours: You are strongly advised to take full advantage of your professor's and ta's office hours.
Classmates: Sometimes a classmate can help. Sometimes you can learn by working out problems together with your classmates.

Help with personal problems which affect your class work:

Talk to the professor or, if appropriate, your college provost.
