Hello and welcome to Math 245!

The website you are at right now will be the the home for all announcements, assignments, and information for our class, so save this link:

We won’t be using Canvas for this course, except perhaps to post some mid-semester grades. Check out the resource links on the right for more information about the class.

Test 2 is coming…

Test 2 will cover everything since Test 1, which means:

  • Chapter 4 (sections 4.1 through 4.5)
  • Chapter 5 (sections 5.1 through 5.4)
  • Chapter 6 (sections 6.1 through 6.3 only)

Start reviewing early if you can! I suggest re-reading the sections, reviewing basic notation, making sure you can do the straightforward homework problems very easily, and trying to strengthen your proof/logic skills. Good luck and post in Slack if you need anything…

Math Colloquium

On Mondays the JMU Department of Mathematics and Statistics hosts a weekly colloquium series. Speakers are sometimes visitors from other schools, and sometimes faculty from our own department. Most talks are designed to be accessible to undergraduates, and you are encouraged to attend if you can! Colloquium talks are about an hour long and start at 3:50pm, in Roop 103. Cookies and refreshments are served at 3:30pm in the same room. Check out the JMU Math/Stat Colloquium Schedule for weekly updates.

If you look at the schedule, you’ll notice that the first speaker is your professor for this course!

In this talk I’ll be speaking about mathematical 3D printing and design, and will bring a lot of interesting 3D printed models to pass around the room. I hope you can come to this fun and accessible talk. I’m also recruiting students for my departmental 3D printing lab and for 3D design and research projects, so please to my talk come if you think you might have an interest in joining my 3D team this semester.

First Day Logistics

Here’s what we’ll do during the first day of class. If you join the class late then make sure you do these things on your own as soon as possible.
