Talk:Rectangular function

A perfect example of a rectangular function that I think should be added is:

$R(x)=\lim _{n\to \infty }(\tan \circ \cos )^{n}(x)$

We already have a much simpler perfect example. Less is more. --Bob K 00:39, 6 June 2006 (UTC)

Nope. — Omegatron 00:42, 8 June 2006 (UTC)

Am I going mad, or is the definition of this simple function just completely wrong? Shouldn't it be

x = 0 if x < 1/2 x = 1 if 1/2 <= x <= 1/2 x = 0 if x > 1/2
