&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Mathworld is a free, online mathematics reference work.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
==Use Mathworld==&lt;br /&gt;
&lt;br /&gt;
===Start Mathworld===&lt;br /&gt;
&lt;br /&gt;
Mathworld is online, or Internet-based. It can be accessed using a Web browser and an Internet connection:&lt;br /&gt;
&lt;br /&gt;
http://mathworld.wolfram.com&lt;br /&gt;
&lt;br /&gt;
An older version of Mathworld are also available in book form from CRC Press, ISBN 1584883472.&lt;br /&gt;
&lt;br /&gt;
===Search Mathworld===&lt;br /&gt;
&lt;br /&gt;
* http://mathworld.wolfram.com/search/ to search Mathworld. The search box can also be accessed from any Mathworld page.&lt;br /&gt;
* Add &amp;quot;site:mathworld.wolfram.com&amp;quot; to a query to search Mathworld using an external search engine such as Google, Yahoo! or Windows Live.&lt;br /&gt;
&lt;br /&gt;
===Article naming and reaching a given article===&lt;br /&gt;
&lt;br /&gt;
Articles in Mathworld are named using CamelCase conventions: for terms that have multiple words, the multiple words are shrunk into a single word and the first letter of each original word is capitalized. Thus, for instance, &amp;quot;prime number&amp;quot; becomes &amp;quot;PrimeNumber&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
The Mathworld URL for a term is given by:&lt;br /&gt;
&lt;br /&gt;
http://mathworld.wolfram.com/CamelCaseName.html&lt;br /&gt;
&lt;br /&gt;
where &amp;#039;&amp;#039;&amp;#039;CamelCaseName&amp;#039;&amp;#039;&amp;#039; is replaced by the actual name. For instance:&lt;br /&gt;
&lt;br /&gt;
http://mathworld.wolfram.com/Triangle.html&lt;br /&gt;
&lt;br /&gt;
http://mathworld.wolfram.com/PrimeNumber.html&lt;br /&gt;
&lt;br /&gt;
http://mathworld.wolfram.com/NormalSubgroup.html&lt;br /&gt;
&lt;br /&gt;
http://mathworld.wolfram.com/GammaFunction.html&lt;br /&gt;
&lt;br /&gt;
To go to an article, either type the full URL or use Mathworld&amp;#039;s site search.&lt;br /&gt;
&lt;br /&gt;
===Organization by topic===&lt;br /&gt;
&lt;br /&gt;
The left-hand column gives a list of major mathematical topics into which Mathworld content is organized. Each topic is divided into subtopics, which may in turn be further divided into subtopics. The lowest-level subtopics contain lists of articles.&lt;br /&gt;
&lt;br /&gt;
A given article may be in one or more subtopic. At the top of each article, the subtopic trees to which the article belongs, are shown. Moreover, a given topic may be a subtopic of one or more topics.&lt;br /&gt;
&lt;br /&gt;
The page listing subtopics/articles of a topic is:&lt;br /&gt;
&lt;br /&gt;
http://mathworld.wolfram.com/topics/TopicName.html&lt;br /&gt;
&lt;br /&gt;
where &amp;#039;&amp;#039;&amp;#039;TopicName&amp;#039;&amp;#039;&amp;#039; is replaced by the actual name of the topic.&lt;br /&gt;
&lt;br /&gt;
==More about Mathworld for users==&lt;br /&gt;
&lt;br /&gt;
See also: http://mathworld.wolfram.com/about/ and http://mathworld.wolfram.com/about/faq.html&lt;br /&gt;
&lt;br /&gt;
Mathworld offers a number of features to augment its main site. It runs on [[Resource:Mathematica|Mathematica]], a software for mathematics-based computation and graphing. Some of the features that Mathworld offers:&lt;br /&gt;
&lt;br /&gt;
* Encyclopedia-like entries on various topics (this is the primary offering)&lt;br /&gt;
* [http://mathworld.wolfram.com/classroom/ Mathworld Classroom]: This gives short entries on topics, such as a definition, a few examples, the expected level of difficulty of the topic, prerequisites. The classroom entry on a Mathworld topic is linked to from its main entry.&lt;br /&gt;
* [http://mathworld.wolfram.com/topics/InteractiveEntries.html Interactive Entries], using graphics applets. The interactive entries on a Mathworld topic are linked to from its main entry.&lt;br /&gt;
&lt;br /&gt;
==Mathworld as a free resource==&lt;br /&gt;
&lt;br /&gt;
===Free access===&lt;br /&gt;
