Today is a group presentation day.

**Come prepared:**

- You should have already uploaded a PDF to D2L of your group homework. I’ve opened a dropbox in D2L where you can upload your groupwork PDFs due tomorrow before class. Log into D2L, go to our course, go to Assessments, Dropbox, and then click on the only open dropbox, which is marked with tomorrow’s date. If this fails, or there is any problem, you can email me your PDF of your groupwork.
- You will hand in your Groupwork Report in class, handwritten is fine.
- You must bring a printed copy of your group homework to annotate while you are watching the presentations (one for each person).

## Today’s class will be a LaTeX workshop held in ECCR 235.

## To do for today’s class:

- Reminder that your group will present on Friday, so make sure you are meeting with your group.
- Please watch this video sum-up of our first in-class proof. It may be helpful in preparing for the groupwork.

## To do for today’s class:

- I made two videos for you to watch! They are each just a couple minutes long:
- Study Hammack, Section 1.1 again. In particular, do more exercises. If I check your homework, I expect to see you have now attempted most if not all of the exercises.
- Study Hammack, Section 4.2. That means read it carefully and create, on a piece of paper, a point-form summary of the section and a list of questions or things you don’t understand. As always, I might check this or use this in class.
- Reminder: you should be meeting with your study group this week. You can always find group assignments under `Resources’ above.

*Late addition:* Here’s a helpful 2 minute video to watch before class if you can:

## To do for today’s class:

- Make contact with your group members and set up a meeting time(s) during Week 2 in preparation for your homework/presentation Friday September 2. I require that you meet once each week, beginning Week 2. You should plan for a 2-hour long meeting, or to meet twice (longer if you plan to be social instead of efficient). You can always find the groupwork assignments and reports under `Resources’ above.
- Study Hammack Section 1.1. The word “study” means you should:
- read actively, asking yourself questions and answering them
- create a point-form a summary of the main points
- try some of the exercises (as many as you feel are helpful, at least a few from each section)
- write a list of the things you don’t yet understand from this first reading. It’s expected that you won’t master it by reading it alone the first time, but the first step is to identify what you need to ask.

- Bring your point-form summary and list of things you don’t understand to class. I may circulate to check you have brought them. I will eventually stop reminding you to do this, but you should always bring your work to class.

## To do for today’s class:

- Make sure you have read all the info on this website (top navigation bar), including goals, syllabus, grading.
- Read Section 4.1 of Hammack. Read carefully and thoughtfully, as always.
- Come up with other examples of theorems. You might consult your calculus book, or the internet. Don’t just copy anything with the title “Theorem” above it. Instead, pick examples whose statements you feel you understand.
- Choose at least one theorem from this book or your examples which is in the form “If P, then Q”. Understand its statement as fully as possible. In particular, answer the following on a piece of paper:
- State the theorem.
- Give examples and an intuitive explanation of all the words used (e.g. function, integer, continuous etc.), so that you can explain their meaning to someone.
- Be able to identify the hypothesis (P) and conclusion (Q).
- Give examples of situations in which the hypothesis is satisfied.
- In each such situation, check that the conclusion is satisfied.

**Reminder: whenever I assign daily tasks, you must bring your work to class, as I may check it for completeness.**
