And one remark. I removed the text you put at concave function. While concave functions and Jensen's inequality are surely important on math olympiads (I used to participate, so I know), that text is not really helpful on that concave function page.

You are however welcome to contribute in other ways. Oleg Alexandrov (talk) 01:26, 1 January 2006 (UTC)
