office hours: m 3-4, w 4-5, and by appointment

  • i will be available in my office on friday 12/14 from 3:00 until about 5:20 for students to see their final exam. students who are unable to come during this time are welcome to make an appointment with me for another time next week or after the break.
  • final exam stats: mean 56.6/90 (62.9%), median 59/90 (65.6%), standard deviation 16.5/90, high score 83/90
  • office hours before the final: m 3-5, t 2-4, and by appointment
  • room assignments for the final exam are alphabetical by family name: students who have been contacted by prof. brown about special arrangements should heed his instructions over the assignments above.
  • the final exam will be comprehensive for the course, covering everything we've done up to and including section 7.2, with an extra emphasis on the material in chapters 6 and 7 (i.e. the post-midterm 2 material). practice finals: spring 2009 solutions (the problems are listed in the document; problem 9(b) is not fair game); fall 2011 and solutions; spring 2012 and solutions. also, here's a review sheet and some brief solutions (thanks, jin!).
  • midterm 2 solutions
  • midterm 2 stats: mean 41.2/60 (68.67%), median 43/60 (71.67%), standard deviation 8.8/60, high score 58/60
  • room assignments for midterm 2: of course, students who have made separate accommodations with the sds office should ignore the above assignments and stick to the arrangement they've made with sds.
  • my wednesday office hour on the day of midterm 2 will be canceled. in its place i will have office hours from 2-4 on the tuesday before the exam. (i will still have my monday office hour from 3-4 as usual.)
  • midterm 2 will cover everything we've done in sections 4.7-5.6 and 5.10. practice exams: spring 2009 midterm 2 solutions (the problems are listed in the document; note that problems 5 and 6b are not fair game); spring 2013 practice midterm 2 and solutions; spring 2013 midterm 2 solutions. you should be prepared to state the following for points: extreme value theorem, mean value theorem, definition of increasing/decreasing function.
  • midterm 1 solutions
  • since hw 6 is due on wednesday 10/17, i am moving my office hours for that day to tuesday 10/16 from 3:00-4:30pm
  • midterm 1 stats: mean 41.1/60 (68.5%), median 44/60 (73.3%), standard deviation 11.2/60, high score 60/60
  • room assignments for midterm 1: of course, students who have made separate accommodations with the sds office should ignore the above assignments and stick to the arrangement they've made with sds.
  • my wednesday office hour on the day of midterm 1 will be canceled. in its place i will have office hours from 2-4 on the tuesday before the exam. (i will still have my monday office hour from 3-4 as usual.)
  • midterm 1 will cover everything we've done in class up to and including section 4.6. practice exams: fall 2011 midterm 1 and solutions; fall 2012 midterm 1 and solutions; spring 2009 midterm 1 solutions (the problems are listed in the document; note that in problems 3 and 4, the trigonometric, exponential, and logarithmic derivatives involved are not fair game for the exam, but you should be able to do similar problems using differentiation rules in the text found prior to section 4.6.)
  • a general remark on the online version of the text: it has been pointed out to us that there are some typos in some of the homework problems in the online version. if you are aware of a discrepancy in a problem between the online and physical versions of the text, then do the problem as written in the physical version. the course policy is that you won't be penalized for doing a "wrong" version of a problem because of a typo in the online version, but you will probably have to sort this out with your ta after the assignment is graded. (the ta's and i don't have access to the online version, so we are unable to identify such typos in advance.)
  • i will have an office hour on 8/30 (the first day of classes) from 2-3

    weekly schedule
    mwf 10:00-10:50, remsen 101, sections 1, 2, 4
    mwf 11:00-11:50, remsen 101, sections 5-9
    here's a guide to the (numerous) abbreviations i use when lecturing

    office hours
    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.

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

    1. t 4:30-5:20, hodson 301, ta: tang
    2. t 3:00-3:50, ames 218, ta: tang
    4. th 3:00-3:50, shaffer 202, ta: he
    5. th 1:30-2:20, hodson 210, ta: he
    6. th 4:30-5:20, hodson 301, ta: zeng
    7. th 3:00-3:50, bloomberg 278, ta: zeng
    8. t 3:00-3:50, hodson 316, ta: zhou
    9. t 1:30-2:20, maryland 109, ta: owen

    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.

    course content
    the departmental syllabus for this course (which we will closely follow, with only small deviations) is here. note that the syllabus has not been updated for the fourth edition of the text, but the changes in the new edition are minor enough that this will have no practical effect.

    homework will be assigned throughout the week and due in lecture 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.

    homework problems will be assigned out of the text, and therefore it is essential to have access to the current (= fourth) edition of the text.

    your solutions should consist not just of the answer to the problem, but an explanation or justification of why your answer is correct. here is a brief note on homework presentation from a previous version of the class.

    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 your solutions must be written up independently and in your own words. copying is a major academic infraction and is strictly forbidden.

    there will be in-class midterms on october 10 and november 14. no calculators, notes, phones, or aids of any sort allowed.

    if you have to miss a midterm for a documented, legitimate excuse, then the corresponding component of your final grade will be calculated by prorating your other exam scores. in case of sickness, you must procure a doctor's note (or some other form of verification) on or promptly after the exam date. there will be no make-up exams.

    final exam
    wednesday, december 12, 9am-noon

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

    study resources
    there are many resources available to you outside of class to help with the course. email
    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.
    Sammy Student
    emails are like letters. they begin with a greeting (like Hi Brian or Dear Professor So-and-so) and end with a closing (like Thanks or Best or Cheers, or Sincerely or Best regards if you want to be a little more formal) followed by your name. it's poor form to use texting abbreviations in emails.

    cell phones
    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.
