4 4  To perform more complex calculations and to fulfill specific requirements, the computer algebra system MAXIMA, which is linked to ONYX, can be used. The [[Netzwerk Mathematik>>url:https://bildungsportal.sachsen.de/opal/auth/RepositoryEntry/5499682817/CourseNode/88308307976325||shape="rect"]] has gathered a number of [[Good-Practice-Examples>>url:https://bildungsportal.sachsen.de/opal/auth/RepositoryEntry/5499682817/CourseNode/93229879750473/||shape="rect"]]. This collection of typical applications, tricks and pitfalls will help you understand how to use the MAXIMA connection in ONYX. Please find below a selection of topics that are described in detail.
