Category: Homework


  • Quiz #8 this Thursday will cover material/homework from sections 5.1 and 5.2.
  • Test #3 will be given in class next Thursday, May 11. It will cover 4.5, 4.6, 10.1, 10.2, 10.4 , and 5.1-5.5.
  • You are still welcome to add Test #2 Solutions posts to the OpenLab for participation credit; don’t forget to tag the “Test #2 Solutions” category.
  • One of my homework problems from last Thursday’s class was to prove or disprove Kazi’s formula for 5.1 homework #10(a). I don’t have a record of my own boardwork from Thursday, so I can’t point out exactly where my mistake was. Kazi’s formula was correct. The proof is actually quite straightforward and I’ve attached a photo of my hand-written work to this post. Let me know if you have any questions.

Reminder – Quiz #4 tomorrow

I hope everyone enjoyed yesterday’s snow day! We will still have Quiz #4 tomorrow on material/homework from Sections 2.3 and 2.4. Since I didn’t hold my usual office hours yesterday, I *might* be able to squeeze some in tomorrow at noon. Send me an email or comment on this post if you would like to see me then.

Announcements from today’s class

  1. Quiz #2 on Thursday, February 23 will cover material/homework from sections 1.4, 1.5, and 1.6.
  2. For section 1.6, the homework questions are #4, #10, #19, #20, and #35. I will change the calendar to reflect this, but the course outline will not be updated.

Welcome and first assignment – Introduce yourself – due Tuesday, February 7

Welcome to your MAT 2440 OpenLab page! All course information will be posted here. From time to time, you will be adding posts yourself as well. Take a look around!

Your first assignment is to add yourself to our OpenLab course and to submit a post introducing yourself to the class. Your post is due by 8am on Monday, February 8.

  2. After you’ve logged in, add yourself to our MAT 2440 class.
  3. From the class OpenLab site you can create a new post by clicking the symbol that looks like a + sign inside a circle at the top of the screen.
  4. Title your post “Introducing [your first name] [your last name].” (You may use just initials if you like, as long as there’s enough information for me to locate you on my official roster.)
  5. From the categories on the right-hand side of the screen, make sure to select “Introduce yourself” so that the rest of us can locate your post later.
  6. Tell us anything you’d like us to know about you! Some suggestions are…
