# Category:Wikipedia articles incorporating text from PlanetMath

This category is not shown on its member pages unless the appropriate user preference (appearance → show hidden categories) is set. |

The mathematics articles in this category incorporate material from PlanetMath. The PlanetMath articles are licensed under the GFDL and are thus compatible with the Wikipedia. Source text is occasionally copied from there to here; see in particular Wikipedia:WikiProject Mathematics/PlanetMath Exchange for a project that attempts to harmonize PlanetMath and Wikipedia mathematics content.

Articles that cite this source should add **{{PlanetMath attribution}}** to the article.

This category is a self-reference and so is part of the Wikipedia project rather than the encyclopaedic content.
