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)[reply]

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

R(x) = 0, if x < -1/2
R(x) = 1, if -1/2 <= x <= 1/2
R(x) = 0, if x > 1/2

????

Is it the values at x = ± ½ that you are concerned about? --Bob K 04:20, 11 July 2006 (UTC)[reply]
