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 the second day 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.
