2. How do I get access to WebAssign?

In order to use the WebAssign homework system, you must purchase access to it.

Did you buy the Hybrid Edition of the text?

If so, then your purchase includes a code for access to WebAssign.

Did you buy just the printed text but not the Hybrid Edition?

Check carefully what you bought. If you are absolutely certain that you did not buy the Hybrid Edition—so that your purchase does not include an access code to WebAssign—then you can buy access to WebAssign on-line at http://webassign.net.

Not sure whether you bought the Hybrid Edition?

Check the 13-digit ISBN-13 number of what you bought. If it’s


then you did buy the Hybrid Edition, after all.
