The "answers to questions" part of this site is not yet properly implemented. As a temporary measure, we are able to provide answers in Word 98 format via e-mail.

As teachers/instructors using this textbook may wish that their students do not have free access to answers, we have decided to screen the requests. To get a copy of these answers, please e mail Roger Perman, using the mail link at the foot of this page. We will forward answers to all teachers/instructors using the text. Answers will be forwarded to other users of the book if a "reasonable" request is made. So please explain briefly in your e-mail the reason why you seek these answers.

At a later date, a password system will be implemented: those with a password (obtainable on request) will be able to access answers by clicking on the links below. This has NOT yet been implemented.
