You are allowed and encouraged to work together on homework. Yet, each student is expected to turn in his or her own work. In general, late homework will not be accepted. However, you are allowed to turn in up to two late homework assignments with no questions asked. When doing your homework, I encourage you to consult the Elements of Style for Proofs. Unless otherwise indicated, submit each of the following assignments via BbLearn by the due date. You will need to capture your handwritten work digitally and then upload a PDF to BbLearn. There are many free smartphone apps for doing this. I use TurboScan on my iPhone.

Reviewing material from previous courses and looking up definitions and theorems you may have forgotten is fair game. However, when it comes to completing assignments for this course, you should not look to resources outside the context of this course for help. That is, you should not be consulting the web, other texts, other faculty, or students outside of our course in an attempt to find solutions to the problems you are assigned. This includes Chegg and Course Hero. On the other hand, you may use each other, the textbook, me, and your own intuition. If you feel you need additional resources, please come talk to me and we will come up with an appropriate plan of action. Please read NAU’s Academic Integrity Policy.


I reserve the right to modify the assignment if the need arises.

  • Homework 1: Read the syllabus and write down 5 important items. Submit a PDF of your written work to the corresponding assignment on BbLearn. Note: All of the exam dates only count as a single item. (Due Wednesday, January 13)
  • Homework 2: Create a free Discord account, accept the invite to our Discord server, and post something about yourself in the #introductions channel. (Due Wednesday, January 13)
  • Homework 3: Complete the problems found here. (Due Wednesday, January 20)
  • Homework 4: Complete the problems found here. (Due Monday, January 25)
