Several of you have asked about this. If you look at the inside cover of your text, you will find a List of Symbols. On the second page of this list, there is a heading "Integers". the first item on the list answers your question and suggests that you check p. 201 for more details :-) From owner-cse191-sp08-list@LISTSERV.BUFFALO.EDU Thu Apr 3 11:41:53 2008 Date: Thu, 3 Apr 2008 11:41:27 -0400 From: "William J.

If you use the Web to help you with the Ackermann-function problem, #7, on HW 9, please be sure to give a full citation to whatever website you linked to. 2. How do you cite a website? Some websites (like Wikipedia) tell you how they want you to do it. In general, you should give the following information: ------------------------------------------------------------------------ author (if known; check the bottom of the webpage) date that the website was last updated (if known; again, check the bottom of the page) title of the website the website's URL date that you linked to the website ------------------------------------------------------------------------ The basic idea behind any such citation is to give your reader enough information that they can find the item for themselves. 3. Here's another piece of advice, from http://www.womenwriters.net/citation.htm "Name of site owner, author or editor. Title of Web Site, Date of latest update of site, if available. Online. Internet. Name of organization or person sponsoring web site. Access or printout date . "If any of the "required" pieces is not available, you should skip it and put what is available; for a site with no title, description of site (such as "Home page"). If a website does not have an author , source of publication (like a University) or editor's name listed, however, you should consider whether or not the site is really reliable, and perhaps make a trip to your library for some more reputable sources." 4.
