Homework

When doing your homework, I encourage you to use the Elements of Style of Proofs (PDF) as a reference. Note: On each homework assignment, please write (i) your name, (ii) name of course, and (iii) Daily/Weekly Homework number.

Daily Homework

The following assignments are to be turned in at the end of the indicated class period. I reserve the right to modify the assignment if the need arises. These exercises will form the basis of the student-led presentations each day. Daily assignments will be graded on a $\checkmark$-system. Exercises marked with * are eligible for the formal Weekly Homework assignments. During class, you are only allowed to annotate your homework using the felt-tip pens that I will provide.

Weekly Homework

In addition to the Daily Homework, you will also be required to submit two formally written proofs each week. You may choose any two problems marked with * that were turned in during a given week to submit the following week. For example, you may choose any two problems marked with a * that were turned in during week 2 for the second Weekly Homework assignment. These problems are due in week 3.

Beginning with the second Weekly Homework, you will be required to type your submission. You should type your Weekly Homework assignments using $\LaTeX$ (see below for more on this), MS Word, OpenOffice/LibreOffice, or Google Docs. However, everyone is required to electronically submit a PDF file via Canvas. I will walk you through how to do this. If you need help with converting your document to a PDF, please let me know.

  • Weekly Homework 1: This assignment is different than the rest. I want you to complete the following tasks. (Due Friday, January 18 by 5PM)
    1. Stop by my office (Room 119 in Adel Mathematics) and say hello. If I’m not there, slide a note under the door telling me you stopped by.
    2. Send me an email at dana.ernst@nau.edu and tell me 3 important things that are in the syllabus. Note: As an example, listing all of the exams dates only counts as one item. Also, if you are the first person to point out a typo in the syllabus, I will give you a bonus point for each typo found. The bonus points will be added to your homework total. This is likely the only opportunity that will arise for you to get bonus points.
  • Weekly Homework 2: Choose any two *-problems from Daily Homework 1-2. You should type your proofs and submit a PDF via Canvas. (Due Friday, January 25 by 5PM)
  • Weekly Homework 3: Choose any two *-problems from Daily Homework 3-4. You should type your proofs and submit a PDF via Canvas. (Due Thursday, January 31 by 10PM)
  • Weekly Homework 4: Choose any two *-problems from Daily Homework 5-7. You should type your proofs and submit a PDF via Canvas. (Due Thursday, February 7 by 10PM)

Using LaTeX for Weekly Homework

If you decide to type your Weekly Homework using $\LaTeX$, I suggest that you use my LaTeX Homework Template. The easiest way to get started with $\LaTeX$ is to use an online editor. I recommend using writeLaTeX, but ShareLaTeX and SpanDeX are other options. The good folks over at writeLaTeX have preloaded my template, so to get started, all you need to do is click the link below.



For a rough overview of some of the basics of $\LaTeX$, you might find my Quick LaTeX Guide useful. Also, I’ve created a couple videos that explain how to get started with my LaTeX Homework Template using writeLaTeX. The first video is here and the second one is here. I ran my mouth too much, but this is what you get when you wing it. Note: The first video walks you through copying the contents of the template from GitHub, but this is unnecessary now that you can just click the button above. If you need any help with LaTeX, please ask.
