Template:MathWorld

The following documentation is located at Template:MathWorld/doc. [<Edit> Template:MathWorld/doc]
[⧼Purge⧽ Template:MathWorld]

The {{MathWorld}} external link template gives a [URL encoded] link to a page on MathWorld.

Usage

{{MathWorld|urlname = PageIndex|title = Page Title|author = Lastname, Firstname|authorlink = authorlink}}

where

• author defaults to: Weisstein, Eric W.
• authorlink defaults to:
  • http://mathworld.wolfram.com/topics/Lastname.html (from Lastname, Firstname)
  • http://mathworld.wolfram.com/about/author.html (for Weisstein, Eric W.)

or

{{MathWorld|urlname = PageIndex|title = Page Title}}

or

{{MathWorld|PageIndex|Page Title}}

where the first parameter is assumed to be urlname, the second parameter is assumed to be title, or

{{MathWorld|Page Title}}

where urlname is inferred by automatically

• removing all spaces, ' and ’ (apostrophe),
• replacing ^ by -,
• replacing * by Star,
• replacing ä by ae, and
• then URL encodes it. (Note that MathWorld uses "title case", while OEIS Wiki uses "sentence case"! Currently, to infer urlname from title, you must use "title case"!)
