Did you ever find that, "pretty funny" button?

Post #5 could use it.

Do you have any idea what T, r, l, K, k and t represent?

At first glance, could be some sort of chaos generator.

What are the names of the variables and constants indicated by the letters? Either that or at least an idea of what scientific/engineering field it relates to.

This information would help greatly!

Re: what's the name of this formula?

The general form of your equation

T= r[(1+tlr)K/k-1]

can be studied by modeling various values of K and k (assuming they are constants), but some info is needed regarding the term tlr .

Is it a constant or a variable? Or is this a typo, and you meant to type t/r ?

Assuming it is t/r I get a graph that has a +∞ asymptote at 0 and goes to 0 as r increases. Similar to a hyperbola.

I should add that the reason I assumed you meant t/r is because if you meant tlr, where tlr is a constant, then the graph is simply a straight line. If tlr is a variable, the equation cannot be identified until you define the properties of tlr.

I should also add that I get a hyperbola when I assume K and k are positive constants and K>k, and that t is a large positive constant. Here is a general form of the graph.

GA to you. While we were all having fun, you have made a serious attempt to answer what appeared a frivolous question. More power to you....

Hey I (and probably others) tried too and even ran down a few potential formula leads on the internet but had no luck. I am wondering if perhaps there are some spelling mistakes.

being varibles, that resembles a hyperbola, with each plot approaching the orgin axis to ∞, but theoritically never meeting it.

We'll expect you to explain how this works in 11 words or less, by the way...

It relates the rotatey of the thrubble to the throom of the congeminating sproggle-loaders. Plot X-Y on the horizole, left over base times k. Plotty-plotty of the infinitigh-to and disclobe of the number-folders in the graph-it. Oh yes. Deep joy!

Guest can you please provide some more information, this formula looks a little familiar but there still isn't enough information given to identify it.

Why should "Guests" jerk us around?

07/15/2010 6:44 PM

Yet another example of "Guest" posting a question and buggering off - leaving many of us well pissed off after trying to help, getting no feedback and asking in vain for more info.

I've been here for a while, and until recently I tolerated this mindless behaviour, but it seems to be becoming more frequent and I'm coming to the conclusion which many have already reached: Guests must register before posting - and definitely before starting a thread.

Well, there's really a simpler solution to that. Don't open any threads started by a Guest. It's not like anyone is making you waste your time. Besides, a registered participant could do the same thing.

I don't feel pissed, just curious about what the guest wanted.

s/He wanted you to tell him the name of this limit for a Markov Chain. Instead, you graphed it for them, and in the process made more than a few of us wish we still had MATHCAD. (OR done better in University...) Milo

Is it the limit for a Markov Chain? I followed that link provided by peterg7lyq, but couldn't see that equation in the link. Likewise didn't see it on wikipedia (not that wikipedia is very reliable). I'm not familiar with Markov Chains.

Yeah, love my copy of Mathcad.
