MAT1375 D073, Fall 2022

Professor Sirelson

Hello and welcome to MAT1375 D073!

Please take some time to explore this OpenLab course site. Use the menu to explore the course information, activities, and help. As the course progresses, you will be adding your own work to the Student Work section.

City Tech email

The college, and your professors will most likely be using your City Tech email to converse with you. Go to this site for all things City Tech email related. You can find your email name, reset your password, and log in from here.

Join this Course

If you’re new to the OpenLab, follow these instructions to create an account and then join the course. You must use your City Tech email to join OpenLab.

Joining OpenLab and becoming a member of this course are 2 different things. Think of it as creating a login for Instagram (ie. joining OpenLab) and then choosing to Follow someone (ie. becoming a member of MAT1375 D369).

Click here, and then click on the “+” next to “Join Now” underneath the picture.

Activate your CUNYFirst Account

If your CUNYFirst account is not activated, go here and click “Claim your CUNYFirst account.” CUNYFirst gives you access to Blackboard and Dropbox, both of which will be used for this class, and probably your other classes as well. Once your CUNYFirst account is set up, you can log in to Blackboard and Dropbox. You will also be able to see which email you have on your CUNYFirst file, which you should change if it is not updated.

WeBWorK Homework System

This semester we will be using WeBWorK for homework. If you have used WeBWorK in the past, then you will be used to the platform to input your homework answers.

The website for WeBWorK can be found here. A login and password will be emailed to you using the email that is found on your CUNYfirst profile. This is why the steps above are so important! If you did not get the email, the login is your first initial (eg. Boba Fett is bfett, Oprah Winfrey is owinfre) and the first six letters of your last name, all lowercase. The password is your Student ID. Please click on the link and make sure you are able to log in. If you did not get the email, or if your login does not work, email me at mailto:


If you have any questions, reach out via email or in Office Hours. If you need help with the OpenLab, you can consult OpenLab Help or contact the OpenLab Community Team.
