Definition talk:Derivative/Higher Derivatives

I've come across the convention that $f^{(0)} := f$. Is this a common notation? If so, should I make a subpage for zeroth derivative, or just add it as a note? --GFauxPas (talk) 15:01, 20 January 2013 (UTC)


 * You might want to add negative numbers as well, extrapolating in the obvious direction, in which case a separate section. This area needs a good refactoring, it seems, as it's a bit unstructured - feel free to add a refactor tag at the top.
