Text: Vector Calculus 6th Ed., Marsden and Tromba.

I am teaching two sections of this course this term. They should run in
parallel, so if you have to miss your class one day, you can *probably*
make it up by attending the other class. But please be aware that the
classes are organic things, and I will probably adjust the exams for
So as a rule, stick to your assigned times. The Zoom URLs are:
sect. 54900: T, Th 9:30-11 with me at https://utexas.zoom.us/j/98539166990
M, W  2 - 3pm with the TA
sect. 54910: T, Th 12:30-2 with me at https://utexas.zoom.us/j/96703407062
M, W  11am-12 with the TA

Teaching assistant: TBA

sect 54900: Wednesday, May 12, 2:00 pm-5:00 pm
sect 54910: Wednesday, May 12, 9:00 am-12:00 noon
There is no provision for taking the final exam earlier or later,
and you must take the exam with the rest of your section.

Course webpage: http://www.ma.utexas.edu/~rusin/427L-21a/ It is unlikely that I will post any important material to Canvas; for any additional information I want to give you outside of class, you should come to this webpage, right in this next section:

### Catalogue Description

Matrices, elements of vector analysis and calculus of functions of several variables, including gradient, divergence, and curl of a vector field, multiple integrals and chain rules, length and area, line and surface integrals, Green's theorems in the plane and space, and, if time permits, complex analysis.

### Pre-requisites

The prerequisite is a grade of at least C- in Mathematics 408D or 408M. Please note that if you had a C- in one of those courses, you have the weakest background in the class and so you should be working hardest and getting the most help and feedback from me and the teaching assistant.

I recognize that the pandemic lockdown has interrupted students' education. It is possible that your calculus courses have had to omit material or adopt more relaxed grading policies. Nonetheless the syllabus of this course is unchanged; in order to thrive in M427L, you really will have to have mastered all the material that is normally taught in a full-year college calculus course.

Your semester grade will be based on a number of components. This structure is designed to encourage you to stay actively involved in the course all the way through the semester. Any adjustments to the schedules or policies will be announced multiple times in lecture and via email and on the course website shown above.

Homework: There will be homework due weekly, done online using the Quest system, located at https://quest.cns.utexas.edu/. This will enable you to get constant feedback on how well you are understanding the material. The homework must be completed online by the date posted, typically about one week after it becomes available.

I will drop the lowest homework grade and average the rest to give you a "Homework Score" of up to 100 points for the semester.

Exams: There will be 2 mid-term exams, to be held during the usual class period, and a comprehensive final exam. The exams will be a mix of multiple-choice and free-response questions. The midterms will be 8-12 questions long; the final is longer but you have 3 hours to complete it.

Because my exams tend to be hard, I have a way to curve the exam scores. I will compute both your raw score and your curved score and whichever is higher for you will be the score I use when computing semester grades. The curving method is simple: I compute the mean, mu, and the standard deviation, sigma, of the class's raw scores, and then a person with a raw score of X will get a curved score of

```   85 + 10 (X-mu) / sigma
```
(with a maximum curved score of 105). This way the mean curved score will be 85 and the standard deviation of the curved scores will be 10. In effect, a person with the average grade gets a "B", and the person whose exam grade is higher or lower by one standard deviation gets an "A" or a "C".

Textbooks, notes, and electronic devices (including phones and calculators) are not permitted during exams. You must have your Zoom camera on and focused on your workspace, but otherwise you may not touch a computer during the exam. Any violation of these rules will result in getting a score of ZERO on the exam.

I expect the dates of the midterms to be March 4 and April 22. The last day of class is May 7. Please mark on your calendars now the time and date of the final exam.

Semester grades: Your numerical grade for the semester is a weighted average of the components above, specifically it is the dot product

``` < 0.30, 0.20, 0.20, 0.30 > . < HW, T1, T2, Final >
```
This number is converted to a letter grade according to the following scale: https://xkcd.com/2329/ Just kidding. I use a pretty standard conversion formula:
 97.0-100 A+ 93.0-96.9 A 90.0-92.9 A- 87.0-89.9 B+ 83.0-86.9 B 80.0-82.9 B- 77.0-79.9 C+ 73.0-76.9 C 70.0-72.9 C- 67.0-69.9 D+ 63.0-66.9 D 60.0-62.9 D- 0 -59.9 F
A majority of students get As and Bs in this class, but every semester there is a significant number of Cs as well as a few lower grades. Of course, this is a hard course, so some low grades are not unexpected, but sadly some students put themselves at risk simply by failing to complete the homework. You have time to do complete it, and permission (even encouragement!) to do it with friends, so it's comparatively easy to get a good grade on the homework. Don't miss this opportunity.

### Policies

Class meetings: Our "lecture" meeting times together are very short so we must make the most of them. Log in daily, with all the materials you need to take notes and work problems. Sit at a desk or table with something to write with. If possible, please choose a distraction-free environment and connect to the Zoom session with your camera on and your microphone off. (Why your camera should be on: https://www.reddit.com/r/UTAustin/comments/hboz5i/ )

The Teaching Assistant will participate in the Zoom classes. He or she will monitor the "chat" box so that will be a place to ask questions --- the T.A. will either answer your question or draw my attention to it; I can't follow the chat box during the lecture. You should also feel free to interrupt me directly! I will usually see a raised-hand icon if you activate it, but I don't mind at all if you simply speak up. (Within reason, of course.)

I am grateful to have the assistance of the Liberal Arts ITS crew, who will be in a recording engineer's booth to give our classes a bit of a professional look. They will record each day's class and save it to Canvas, under the "Lectures Online" link. (Recordings appear later in the day.) They have also set up the Online Course Tech Support tab on the navigation panel; you may go there to get help for any technical issues you have that may prevent you from accessing materials on your Canvas course. (You will initially be greeted by an AI chatbot which can answer most questions, but if not you will be connected with a live support representative from LAITS.)

Class Recordings: Class recordings are reserved only for students in this class for educational purposes and are protected under FERPA. The recordings should not be shared outside the class in any form. Violation of this restriction by a student could lead to Student Misconduct proceedings.

This class runs "live" (i.e. "synchronously"): I expect you to be participating in the class every day at the appointed time. Attendance is not mandatory. But who are we kidding? We're going to work through the entire textbook in just 30 class meetings. At the pace of this class, any time you miss a class, you are at least a whole section behind! That's hard to make up. Plus, if you are (to take a common example) paying in-state tuition for 12 undergraduate credit-hours in the College of Engineering, the tuition alone costs you \$71 for every one of those 40 class meetings. Are you really going to throw away \$71 you have already paid, so that you can turn off Zoom and take a nap?

Piazza: There is a tab in Canvas that takes you to Piazza, a discussion forum for the students in the class. This is a good place to ask questions when class is not in session. Other students can answer your question(s) when they log in. I will try to visit the forum occasionally to help out with the discussion (and in particular I may need to improve some student answers a bit for accuracy or clarity).

Make-ups: It is in general not possible to make up missing quizzes or homework assignments after the due date. If you believe you will have to miss a graded event, please notify me in advance; I will try to arrange for you to complete the work early.

Students with disabilities: The University of Texas at Austin provides upon request appropriate academic accommodations for qualified students with disabilities. For more information, contact the Office of the Dean of Students at 471-6259, 471-4641 TTY.

Religious holidays: If you are unable to participate in a required class activity (such as an exam) because it conflicts with your religious traditions, please notify me IN ADVANCE and I will make accommodations for you. Typically I will ask you to complete the required work before the religious observance begins.

Academic Integrity. Please read the message about Academic Integrity from the Dean of Students Office. I very much prefer to treat you as professionals whose honesty is beyond question. But this has proven difficult, especially with students taking exams remotely. I have reported students to the Dean for cheating and they have had to bear the consequences; I will do so again if I must. Don't be that person!

Campus safety: Please familiarize yourself with the Emergency Preparedness instructions provided by the university's Campus Safety and Security office. In the event of severe weather or a security threat, we will immediately suspend class and follow the instructions given. You may wish to sign up with the campus alert programs.

Counseling: Students often encounter non-academic difficulties during the semester, including stresses from family, health issues, and lifestyle choices. I am not trained to help you with these but do encourage you to take advantage of the Counselling and Mental Health Center, Student Services Bldg (SSB), 5th Floor, open M-F 8am-5pm. (512 471 3515, or www.cmhc.utexas.edu

Add dates: If you enroll within the first four class days of the semester, and have missed any graded material, I will adjust the weighting of your graded sections accordingly so that you are not penalized. No such accommodation is made for students who enroll on the 5th day or later. (Such students must enroll through the MPAA advising center in PMA, and ordinarily I do not admit students who ask to enroll then if they have missed any graded activities).

Drop dates: Jan 22 is the last day to drop without approval of the department chair; Feb 3 is the last day to drop the course for a possible refund; Apr 5 is the last day an undergraduate student may, with the dean's approval, withdraw from the University or drop a class except for urgent and substantiated, nonacademic reasons. For more information about deadlines for adding and dropping the course under different circumstances, please consult the Registrar's web page, http://registrar.utexas.edu/calendars/20-21/

Quest: This course makes use of the web-based Quest content delivery and homework server system maintained by the College of Natural Sciences. This homework service will require a \$30 charge per student per class for its use, with no student being charged more than \$60 a semester. This goes toward the maintenance and operation of the resource. Please go to http://quest.cns.utexas.edu to log in to the Quest system for this class. After the 12th day of class, when you log into Quest you will be asked to pay via credit card on a secure payment site. Quest provides mandatory instructional material for this course, just as is your textbook, etc. For payment questions, email quest.billing@cns.utexas.edu.

Computers: We don't make use of sophisticated software in this class, but if you find this interesting, you are welcome to use the department's computer facilities. Our 40-seat undergrad computer lab in PMA 7.122, is open to all students enrolled in Math courses. Students can sign up for an individual account themselves in the computer lab using their UT EID. We have most of the mainstream commercial math software: Mathematica, Maple, Matlab, etc., and an asortment of open source programs. If you come to my office you will see me use some of this software to help illustrate concepts. Please see me if you would like more information.

Sharing of Course Materials is Prohibited: No materials used in this class, including, but not limited to, lecture hand-outs, videos, assessments (quizzes, exams, papers, projects, homework assignments), in-class materials, review sheets, and additional problem sets, may be shared online or with anyone outside of the class unless you have my explicit, written permission. Unauthorized sharing of materials promotes cheating. It is a violation of the University’s Student Honor Code and an act of academic dishonesty. I am well aware of the sites used for sharing materials, and any materials found online that are associated with you, or any suspected unauthorized sharing of materials, will be reported to Student Conduct and Academic Integrity in the Office of the Dean of Students. These reports can result in sanctions, including failure in the course.

Sanger Center resources: The Sanger Learning Center offers resources for students seeking academic success. Among them, students may schedule unlimited tutoring appointments in several subjects including M427L.
