An Extendable Essay on the Sage Computer Algebra System and an Editor for Creating Extendable Essays
摘要
Abstract
An extendable essay is a special format of electronic texts that is more convenient for reading than hypertext. To facilitate the creation and editing of extendable essays, an editor program implemented as a web application is proposed. Using this editor, an extendable essay on the Sage computer algebra system is written. Sage seems to be a good choice for the users who are not familiar with computer algebra systems.
