Usage

{{MathWorld |id= |title= |author= |access-date= |ref= }}

where all parameters must be in title case.

Params

|id= - e.g.: GammaFunction
|title= - e.g.: Gamma Function; defaults to page name
|author= (optional) e.g.: John Doe (default is Eric Wolfgang Weisstein)
|access-date= - for use in citations
|ref= - to mark a reference anchor name to match {{sfn}}-style references
|mode= - "cs1" (the default) or "cs2" for Citation Style 1 or Citation Style 2

HTML anchor

The template uses a HTML anchor of #Reference-Mathworld-(article name). Thus, to reference a MathWorld article entitled "Gigantic Prime" using Harvard style references, use ([[#Reference-Mathworld-Gigantic Prime|Weisstein]]) which will display as: (Weisstein). When clicked, the link is to the reference in the following example.

Two article version:

Code:{{MathWorld2|title = Prime Number|id = PrimeNumber|title2 = Primes|id2 = Primes|access-date={{subst:TODAY}}}}
