**Term:**Fall 2020.**Course code:**AMATH231**Prerequisite:**MATH 237/247, Calculus III**Instructor:**Achim Kempf**Teaching Assistants:**Kaiwen (Kevin) Jiang, Richard Lopp, Dinesh Siewnarine**Lecture times and location:**

Videos will be posted Mondays, Wednesdays, Fridays by the end of the day, see below for the links.

**First lecture:**Wednesday, 9 September 2020**Office hours with Prof**: Fridays 1-2pm via Zoom**Tutorials with the TAs (Kaiwan, Richard or Dinesh):**

- Wednesdays 10-11am
- Links to the Tutorials and their recordings are on this page.

**Instead of email, this course uses the online discussion forum Piazza for use by students, TAs and prof:**

Please sign up, it is free.**The link is here: Piazza.**- Using Piazza is better than emailing the TAs or the instructor because by using Piazza, all can benefit from the discussion. If you wish, you can post anonymously.
- Particularly good answers from students to student questions may receive bonus points.
- Of course, do not discuss the solutions to a homework exercise that is still due.

**Grades:**Homework 20%, Midterm 30%, Final 50%.**Midterm exam:**

**Logistics:**

**Friday October 23rd**- Time of day, duration and procedure will be announced here closer to the date.
**You will need your Watcard.**

**Content:**

- All the material in the textbook up until reading week is examinable.
- This means all up to and including Sec. 3.2.1 (i.e., up to the top of page 77 in the notes).
**Important**: Be prepared that some of the questions may be of this format:

- (a) Give a simple example of ABC
- (b) For the example you gave in (a), calculate XYZ.
- The example is expected to be your own example, i.e., it should be at least a little different from the examples in homeworks and lecture notes.

**Final exam:**Day and logistics will be announced here.

The lecture notes will be self-contained and only the materials covered in the lecture notes and lectures will be examined.

But of course, you are encouraged to read other textbooks and sources as well. Sometimes it is helpful see things from different perspectives. For example, the standard calculus textbook by J. Stewart has a review of vector calculus with useful exercises. For a more in-depth treatment, have a look, for example, into the textbook Vector Calculus by M. Lovric (Wiley, 2007). There are tons of alternatives.

In brief, we complete continuous calculus. At the end, we show that, even though it is counter intuitive, continuous structures can be entirely equivalent to discrete structures. Real-life applications are ubiquitous.

Concretely, we first complete calculus by extending integration and differentiation techniques to curved structures such as curved paths and surfaces. The main concepts and results here are vector fields, line and surface integrals and the three famous theorems - Green's theorem, Gauss' Divergence theorem and Stokes' theorem. Applications, e.g., to physics and engineering are emphasized throughout. The second part of the course introduces Fourier analysis, that is, the remarkable fact that a huge classes of functions, in fact essentially all those functions that occur in engineering and physics, are linear combinations of sine and cosine functions. This, in turn, leads to the Shannon sampling theorem which shows that continuous functions can be equivalent to discrete structures. This fact is at the heart of information theory. For example, every phone uses Shannon's theorem to transform back and forth between real-life continuous music or speech or video signals and discrete data in a file.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land promised to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
