The proprieties listed here http://en.wikipedia.org/wiki/Even_and_odd_functions#Basic_properties are quite plain.. Somoene should add a short proof for each propriety.{{unsigned|stdazi}}

:I'm not sure that's a good idea. The properties are ''so'' simple, I think the proofs can be left to the reader. Perhaps a proof or two could be given, but we don't need one for ''every'' property. [[User:Doctormatt|Doctormatt]] 23:07, 11 August 2007 (UTC)

== Definitions ==

I think we should make the definitions of odd and even functions more strict. My suggestions are:

<br>Let <math>f:A\to\mathbb{R}</math> where <math>A\subseteq\mathbb{R}</math> ƒ is even if and only if <math>f(x)=f(-x)</math> for all <math>x\in A</math>

<br>Similarily ƒ is odd if and only if <math>f(x)=-f(-x)</math> for all <math>x\in A</math>
