here's a guide to the (numerous) abbreviations i use when lecturing

office hours are times for you to stop by to discuss anything related to the course -- questions about material in the lectures or on the homework, gripes about exams, logistical matters, etc. to see me during my scheduled office hours, just show up, no appointment necessary. to see me at another time, talk to me or send me an email to make an appointment. your ta will also hold at least one regular office hour per week.

you will be assigned to one of six (creatively numbered) recitation sections for the course (t = tuesday, th = thursday):

1. t 1:30-2:20, gilman 119, ta: lang

2. t 3:00-3:50, maryland 309, ta: lang

5. th 3:00-3:50, croft g02, ta: dees

6. t 4:30-5:20, hodson 313, ta: wang

7. t 3:00-3:50, bloomberg 176, ta: wang

8. th 1:30-2:20, maryland 202, ta: vanblargan

the aim of the recitation sections is to complement the lectures -- which will be fairly theoretical in nature -- with a more practical, hands-on approach to the material. in particular, recitations are a good place to discuss homework questions. in addition to the section meeting, each ta will have one office hour per week, as listed above.

Claudia Neuhauser,

the departmental syllabus for this course (which we will closely follow, with only small deviations) is here. the syllabus for the precursor to this course, math 106, may also be of use.

homework will be assigned throughout the week and due in class on fridays. it will be returned at your recitation section. no homework will be due the weeks of midterms. please staple your assignment and write your name and section number on it.

each assignment will be graded out of thirty points: five of the assigned problems will be graded out of five points each, and the overall completeness of the assignment will be graded out of an additional five points.

late assignments will not be accepted under any circumstances, but your lowest two homework scores from the semester will be dropped. you are encouraged to collaborate with each other on homework problems, but

there will be in-class midterms on march 7 and april 18. no calculators, notes, phones, or aids of any sort allowed.

if you have to miss a midterm for a

wednesday, may 9, 9-noon

20% homework, 20% each midterm, 40% final exam

there are many resources available to you outside of class to help with the course.

- office hours (see above)
- the math help room, open monday-thursday 9-9 and friday 9-5.
- tutoring at the learning den
- peer-led learning at pilot

by far, the best way to communicate with me (and your other professors) outside of class is email. if don't have a lot of experience writing emails, here's a sample of something you might want to write in this class:

Hi Brian, Could I please make an appointment with you for sometime Thursday afternoon or Friday? I still have some questions after office hours. I'm free after 3:00 on Thursday and all day Friday, if there's any time that works for you. Thanks, Sammy Studentemails are like letters. they begin with a greeting (like

it goes without saying, but here it is anyway: please put yours in vibrate or silent mode in class.

if there's something i or the ta's could be doing better, we want to know about it -- and right away, so that we have a chance to fix it. if you'd like to pass along your suggestions without passing along your name, please send them to the math department director of undergraduate studies, professor brown, and kindly ask him to forward them to me anonymously.

The strength of the university depends on academic and personal integrity. In this course, you must be honest and truthful. Ethical violations include cheating on exams, plagiarism, reuse of assignments, improper use of the Internet and electronic devices, unauthorized collaboration, alteration of graded assignments, forgery and falsification, lying, facilitating academic dishonesty, and unfair competition.

Report any violations you witness to the instructor. You may consult the associate dean of student conduct (or designee) by calling the Office of the Dean of Students at 410-516-8208 or via email at integrity@jhu.edu.
