MATH 200:921 Multivariable calculus.
Summer term 1 2017/18

Instructor: Roberto Pirisi
Email: rpirisi [AT] math.ubc.ca
Classes: Tuesday, Thursday and Friday 10 am to noon and Wednesday 10 am to 11, room LSK 200
Office hours: Tuesday and Thursday 2:00 to 4:00 pm, in my office (MATHX 1220).

Textbooks:

Exams and Marking

Course mark will be based on the Homework Webwork (15%), five in-class quizzes (35%), and the final exam (50%). The final exam will cover the entire course. No calculators, electronic communication devices, books, notes or aids of any kind will be allowed for exams. Students are required to bring ID to all exams.

Policies:

  • All exams are closed book. Calculators will not be permitted. Each student is allowed a single one-sided formula sheet.
  • The worst of your quizzes will be dropped from the average. If you miss a quiz that will be the one that is dropped. In case of a justified absence (with a doctor's note or prior consent from me) at most one more quiz can be dropped from the average.
  • Webwork assignments generally close at 11:59 pm on Tuesday and Friday night (please look at the dates carefully in case there are some deviations). No extensions are possible.
  • If for any reason you have to miss the final exam, it is the university-wide policy that you need to apply for "standing deferred" status through your faculty. Missed finals are not handled by the instructors or the Mathematics Department.

    • Homework

  • Homework assignments should be submitted online through Webwork (Link to the course). To enroll in the WebWork course you must access it through Canvas.
  • Please use Piazza as the main resource for help with webwork-related and other questions. It is a forum, which will be monitored by our TA, where you can post questions and answers about webwork. Please use the "e-mail instructor" button in webwork *only* if the question is not answered on Piazza, and you posted it and did not receive an answer. Sign-up link for our class on Piazza.

    Getting help

  • In addition to the office hours, please take advantage of the Math Learning Centre drop-in tutoring. Do not wait till the exams -- if you feel uncomfortable with any of the material, talk to your classmates, talk to the instructor, and come ask questions at the Math Learning Centre.
  • For technical problems with webwork, Piazza registration, or exam conflicts, please e-mail me.

    Resources

  • Lecture notes
  • You can use Wolfram Alpha -- it is a wonderful tool for plotting graphs of functions of two variables, for example. If you want to visualize, for example, the surface x^2+xy-y^2+3z=0, just type in "plot (x^2+xy-y^2+3z=0)". A note about Webwork and Wolfram Alpha: there will be many problems in Webwork which require thinking and which Wolfram Alpha cannot do; for the more mechanical ones that it can do, if you just use the software and copy the answers, it detracts from your learning. You might get a few extra points for the webwork problem, but you'll certainly lose much more on the exam for not having that skill. So use this great software to your advantage (to help you visualize the objects we study, and to learn), not to your disadvantage (to cheat on Webwork).
  • See review materials for the exams below the "Announcements" section on this website.
  • Math Learning Centre drop-in tutoring.

    Announcements:

  • Final will be on June 26, at noon in Buch A101.
  • Quiz 1 on Tuesday 5/21 Quiz Solutions.
  • Quiz 2 on Tuesday 5/28 Quiz Solutions.
  • Quiz 3 on Tuesday 6/05 Quiz Solutions.
  • Quiz 4 on Tuesday 6/12 Quiz Solutions.
  • Quiz 5 on Tuesday 6/19 Quiz Solutions.

    • Review materials for the Final exam

    Here are some handouts to help you review (please not that the "detailed list of topics" handout reflects my personal view of which topics are important; other instructors might have emphasized different topics).
  • The detailed overview of topics.
  • a table of integrals and useful integration techniques .
  • You can access old final exams without solutions at: The Math department website . The Math Club sells solution packages in MATX 1119. Please see their Facebook page for the schedule.
  • Notes from the document camera, from a review session from 2013.
  • There are three giant Webwork sets:
  • Part 1 : a collection of problems from the beginning of the course, on vectors and geometry of space;
  • Part II : a large collection of problems about functions, partial derivatives, level curves, gradients, and critical points and optimization probelms, including Lagrange multipliers.
  • Part III: A collection of integrals in 2 or 3 dimensions, in all kinds of coordinates. These are pdf printouts generated by webwork for one user (your problems will be slightly different). Use these files to identify problems of interest, and then you can try your answers in webwork. These Webwork sets ARE NOT FOR MARKS.
  • Final from 2003, with solutions . Ignore Problem 8.
    Some old midterms (still good for reviewing many topics):
  • Midterm 1 for Math 263, 2005. (Ignore Problem 2).
  • Midterm 1 from 2007. (Ignore Problem 2).
  • Midterm 1 from 2012 (this one was too easy, though -- you can expect a slightly harder exam this year and it will cover more).
  • Midterm 1 from 2013 with solutions
  • Midterm 2 from 2013 with solution (only look at problems 1(a)(b), (c) and 3).
  • Midterm from 2015 (with solution)
    In the exams below, from Math 263, ignore all the problems about: vector functions, surface area, arc length, or vector fields (this course had more material).
  • Midterm 2 from 2004 but for Math 263
  • Math 263 final from 2007. Ignore Problems 2,5,6.
  • Another old Math 263 final Ignore problems 5,6,7,8.
