Argh! What's the word?

I'm thinking of something I did about in control systems, when a curve tends towards zero, there's a name for it, but I can't remember what it was.

[andyandy]

converge to zero?! :)

[Badger]

Or maybe asymtotic?

I know that doesn't tend towards zero, but it's a cool math word anyway!

[Jeff Corey]

Negative feedback.

"Asymptotic" is probably what you mean.



:boxedin:

[Jeff Corey]

Asymptotic is when the slope of the curve approaches zero.

[MetalPig]

Asymptotic is when the slope of the curve approaches zero.
Not necessarily.
y = x + 1/x asymptotically approaches y=x as x gets larger, yet its slope approaches 1.

[Jeff Corey]

Right. I was thinkinking of positively or negatively accelerated monotonic functions like growth and decay curves.

That was the one I was thinking of. Shows how much I was paying attention in class though.

Cheers everybody.
