This course is MAT 2680, Differential Equations, taking place in the Spring 2019 semester with Professor Reitz. We will be using this website in a variety of ways this semester – as a central location for information about the course (assignments, review sheets, policies, and so on), a place to ask and answer questions, to post examples of our work, and to talk about mathematics, physics, reality and so on.

**Getting Started**

Anyone on the internet can look around the site and see what we are doing, and even leave a comment on one of the pages. However, only **registered users** can create new posts and participate in the discussion boards.

**How do I register?**

You will need to do two things:

- If you have not used the OpenLab before, you must first create an account. You will need access to your citytech email address for this. Detailed instructions for signing up on the OpenLab can be found here.
- Once you have created an account on the OpenLab,
**log in**and then join this particular course,*2019 Spring – MAT 2680 Differential Equations – Reitz*. To do this, first click the “Course Profile” link at the top left of this page (just above the picture). Then click the “Join Now” button, which should appear just underneath the square picture of a peaceful natural scene.
