My Weekly Schedule

Return to Homepage


Calendar: This provides a rough schedule for the semester. The sections to be covered and the dates and order in which they occur are subject to change.

Assignments: These problems are to be turned in for a grade.

Supplemental exercises: These exercises provide extra practice on the basic methods and concepts covered in a given section. You should complete as many as necessary to master the given technique. They will not be graded. Do not turn these in.

Keys to quizzes and exams

Basic derivatives and integrals: You may use this for exams.

Midterm 1 review

Midterm 2 review: revised (removed reference to material from chapter 14).

Midterm 3 review: revised (material from section 15.2 will not be covered on midterm 3)

Final exam review


Solutions to odd-numbered problems.

The Geometry of Vector Calculus: Developed by Tevian Dray and Corinne Manogue at Oregon State University (see also the Vector Calculus Bridge Project). A resource for those interested in the "differential" point of view.

Parametric curves in 3D By Barbara Kaskosz at the University of Rhode Island.

Surface/level curve grapher By Barbara Kaskosz at the University of Rhode Island and Doug Ensley at Shippensburg University.


Fri 12/9: here is what's been suggested as possible questions for the final exam.
Tues 12/6: Office hours this week: Wednesday 11:30--3:30, Thursday 1:00--3:00, Friday 11:30--2:00. On Wednesday and Friday I will be coming from a class, so I may be a little late getting back to my office. If I'm not in my office during these times, I've probably stepped out to get coffee and will return shortly.
Mon 12/5: The plan for this week will be as follows. Monday and Tuesday will be the final days of lecture. Wednesday will be devoted to a couple of short exercises to help get you into "review mode", and you will have a chance to check the homework, quiz and exam scores I have entered for you in my spreadsheet. Friday will be an open session; bring questions.
Wed 11/30: Regarding homework problems involving Stokes' Theorem. Feel free to use any surface that satisfies the hypothesis.
Tues 11/29: Here is a list of the gradient, curl and divergence with respect to Cartesian, cylindrical and spherical bases.
Tues 11/15: Here's the example of finding a potential function for a conservative vector field from yesterday's class.
Thurs 11/10: Exam 3 is graded and will be returned in class on Friday. Stats (out of 50 points total):
Tues 11/8: Here's a better way to compute line integrals for flux across closed plane curves. Also, if you want an example of a non-zero flux integral, try computing flux of the field F = x i + y j across the unit circle (or, for that matter, across the ellipse from today's class).
Tues 11/1: Material from section 15.2 will not be covered on midterm 3 this Friday nor will it included in assignment 10. Material from section 15.1 is fair game. The exam review and assignment have been updated.
Mon 10/31: Please prepare 2--3 questions that you think would be good questions for this exam, and bring them to class on Wednesday. Be sure to include what the questions would be testing and why you think they are "good" questions.
Sun 10/30: The review for midterm 3 is posted. Also, I've opened a forum on the Blackboard discussion board for people to list the questions they would like to discuss during the review on Wednesday. The idea is try to reach a class consensus about what people want to talk about before the review.
Wed 10/26: I've been looking at the problems for section 14.8, and it seems that the transformations for a change-of-variables are given. This being the case, I'd like to open up the first half-hour of class on Friday (before the quiz) to questions. If no-one has any questions, I will have another example of a change-of-variables ready.
Mon 10/24: ANIMALS
Thurs 10/20: Exam 2 stats (out of 50 points total):
Wed 10/19: Assignment #8 is due this Friday (10/21). I've corrected the typo on the assignments page.
Wed 10/12: I will have extra office hours tomorrow from 12:00--1:30pm.
Sun 10/9: The review for the second midterm has been posted.
Fri 10/7: The key to today's quiz has been posted. Also posted is a solution to the problem we worked on in class.
Fri 9/30: Someone left their textbook in class today. It can be picked up in the Math Department office (235 Math/Geoscience Building). Also, if you have any feedback on the worksheet we did in class today, I'd be very interested in hearing it.
Tues 9/26: To get a rough estimate of your current course standing:
  1. Add your first three quiz scores, divide by 30 and multiply by 0.3 (remember to add two points to your quiz 1 score if you turned in the self-assessment);
  2. divide your first exam score by 50 and multiply by 0.6;
  3. add your first four homework scores, divide by 8 and multiply by 0.1;
  4. add 1, 2 and 3, and multiply by 100.
Example: quiz 1 (adjusted) = 7, quiz 2 = 8, quiz 3 = 5, exam = 37, hw 1 = 2, hw 2 = 1, hw 3 = 0, hw 4 = 2:

[( 7 + 8 + 5 )/30]*0.3 + [37/50]*0.6 + [(2 + 0 + 1 + 2)/8]*0.1 = 0.7065
0.7065*100 = 70.65

If I were to assign grades now, the breakdown would be:
A: 90 -- 100
B: 80 -- 89
C: 70 -- 79
D: 60 -- 69
F: below 60

Wed 9/21: The key to the first midterm is posted. Friday's quiz will be over the material in section 13.1 only.
Sun 9/18: Now that the first exam is under our belts, I would like to know your opinion about what type of in-class exam review you think would be most helpful for future exams. I've created a survey on Survey Monkey. You can participate here. Please respond only once.
Thurs 9/15: I will be in my office tomorrow (Friday 9/16) from 9:30--10:30 if you have last-minute questions before the exam.
Thurs 9/15: STUDY BREAK. Sorry for the late notice, but there's going to be a talk at the SUB this afternoon that could be good: "Geometric Gems: Appreciating the Timeless Beauty of Mathematics". The speaker is Michael Starbird from the University of Texas at Austin. More information here.
Tues 9/13: There's now a link to an online applet for graphing parameterized curves in space (above, under "Links").
Fri 9/9: The review for the first midterm is now posted above.
Tues 9/6: Here is the follow-up self-assessment for quiz 1. Please complete this and turn it in to me by the beginning of class this Friday (9 September). Well-considered responses will be worth up to two points added to your quiz 1 score (with a maximum adjusted score of ten points). Please be as specific as possible.
Fri 9/2: Examples of computing the infinitesimal displacement vector can be found here. I've also posted a link (above, under "Links") to the wiki book "The Geometry of Vector Calculus". This provides some handy supplementary material for our class.
Tues 8/30: Office hours have changed (see above).
Thurs 8/25: Homework formatting. At the top of the first page of each assignment, please include:
in that order, and each on a separate line. Begin each section on a new page, and clearly indicate the section number at the top of the page. Do not divide your pages into multiple columns (if you have already begun writing up Assignment 1 and are using more than one column per page, you do not need to recopy your work).

Tues 8/23: There is now a discussion forum open on Blackboard. You can subscribe to the forum and receive e-mails at your Boise State account as new posts are added. I've started with a "general discussion thread". You may also begin new threads within the forum -- for example, if you want to discuss a particular homework problem.
Sat 8/20: The syllabus and calendar are now posted.
Wed 5/11: Welcome to Math 275.
