1.1.3
Step 1
Do Step 1 from the PDF file, in which you will be asked to load the corresponding LaTex file.
The purpose of this HW is to ensure you are are able to LaTex the ER 1.1.3, which is basically Step 2 and is due Wed. 1/11. If you are having troubles with Step 1, after class on Monday I can help you. It would be helpful for you to bring your laptop if you have one. Nothing to hand in but if you cannot do Step 1, you will not be able to do your ER homework so let's get Step 1 figured out ASAP.
Tue
1/10

at 7 pm

If you are having troubles with Step 1 of the HW due 1/9,
then join the Zoom meeting at 7pm this evening (Tue 1/10).
Recall, you cannot do ER 1.1.3, which is due tommorrow (1/11), unless you can do this Step 1. Over Zoom, students can share their screen so we can figure out what you need to do on your computer for Step 1. Recall, the Zoom link is on Blackboard (see left side column).
My apologies for not being able to give you a time of this meeting in class yesterday but an email just arrived telling me the time of a meeting I have to attend today.
Wed
1/11
Just omit your PIN for today's homeworks. PINs will be assigned after the roster is fixed.
Recall due date are not usually posted but is here since students are still adding the class.
1.1 Study Guide Homework for this section.
First read the Study Guide (SG) HW Instructions posted above.
FYI: Correct solution to Exercise 1.1.2 (solution in back of book is wrong).
1.1.3
Step 2
First read the Exercise (ER) HW Instructions posted above.
For the variant/hints, see the PDF file. To LaTex the ER, load this LaTex file to Overleaf.
(These above two posted files are the same files posted for Mon. 1/9.)
Wed
1/18
Just omit your PIN, which will be given to you after the roster is fixed.
The place to enter your name on an ER is towards the top of the Latex file (about line 15).
If you double click (with left mouse key) at a place in the PDF file, then Overleaf indicated to you the corresponging place in the TeX file. This feature makes it easy to compare the PDF output to the LaTex input.
1.2 Study Guide Homework for this section. (As usual, follow the Study Guide HW Instructions posted above.)
1.1.5 For the variant/hints, see the PDF file. To LaTex the ER, load this LaTex file to Overleaf.

GW § 1.2 Group Work   (Direct proof of a conditional statement using def. of even/odd.)
Change of what was announced in class.
For your group's one Lemma, before class do just the Thinking Land (directly on the class handout where it says Below space is for your Thinking Land). Bring your Thinking Land to class on Monday. Then in class on Monday, be prepared to help your group write a proof for your Lemma. So you do the Thinking Land before class and during class your group will write the proof together.

LL Latex Lessons   (LaTex Help by Example).
  1. Read the link Latex Lessons page, which is also posted on the course homepage.
  2. On Overleaf, create yourself a new project named Latex Lessons.
  3. Into your Overleaf project Latex Lessons, load each of the five (5) Latex Lessons LaTex files (FileName.tex) that are posted on the Latex Lessons page.
Then on Overleaf, for each of the five lessons:
  1. (re)compile the lesson, which will produce the corresponding PDF file in Overleaf's last column
  2. actively read the PDF file, comparing the PDF output to the Latex input.

To Hand In
Basically, some kind of evidence that you did this assignment. List each of the 5 lessons and then under a lesson take some notes. Your notes can just be in the form of student notetaking (so handwritten and need not use complete senetences). You can just jot down items you do not want to forget. Be sure to have at least 2 take-aways/noted-items for each lesson.

WG It is highly suggested you get started on the WG homework due 2 days after this HW (so on Wed 2/1). Note there are several ER's due on 2/1.
