Enhanced WebAssign (EWA) is an on-line system for answering homework problems. There will be three to four WebAssign assignments per week. Completion of these assignments is a required part of the course. It is your responsibility to make sure you complete each assignment by the posted due date. These due dates are shown in WebAssign, and are also posted on the schedule page of this website. Assignments are due at 11:59 pm on the due date.
You can get started immediately, even before purchasing the text and WebAssign access!
The first assignment is due Wednesday of the first week of class, so do not wait!
There is a two-week trial period in the beginning of the semester during which all enrolled students may use WebAssign without an access code.
If you took Calc 1 or Calc 2 here at CU, then your existing textbook and access code work for this course. Otherwise, you can purchase a Cengage subscription either at the bookstore or directly from the pubisher. The subscription includes the following benefits:
- WebAssign access and the ebook for Math 2400. (It also includes access to any other Cengage course you are taking.)
- Auxiliary texts, like student solutions manuals
- An optional one-semester free rental for a hard-copy of the textbook; this costs $7.99 for round-trip shipping.
You may also purchase a binder-ready (loose-leaf) copy of the textbook from Cengage for approximately $45 (free shipping)
Accessing Webassign (EWA)
If you registered for the course by January 10, then you should already be enrolled in WebAssign. Your username is the same as your Identikey username, and your password is your Identikey password.
If you added the course after January 10 or if you have switched sections, then email math-help@Colorado.edu
to become enrolled in WebAssign. Include your first and last name, your CU email address, your Identikey username, and the course and section number you are enrolled in.
To log on to WebAssign, visit https://www.webassign.net/colorado/login.html
The first time you log in, you will be prompted to create a Cengage account (if you do not already have one). Enter your CU email address (not a personal email address), and a password. This password is not linked to your IdentiKey. Then once the Cengage account is created and linked to your IdentiKey it will allow you to log in with either method and view all of your courses being run through Cengage. For more information, see this detailed PDF on how to log in
For problems with your WebAssign account, visit the Cengage student support page.
They also offer 24/7 tech support: 800-354-9706
If you drop the course during the first two weeks of the semester, contact WebAssign, who will release the code back to you for a refund from your original place of purchase.
