Talk:Omega constant

letter The fact that it is called the omega function makes me think someone mistook the letter ω, a vowel, for the letter w, because of visual similarity. Is that what happened? Michael Hardy 20:42, 12 Feb 2004 (UTC)

Comparison to the golden ratio[edit]

"It has properties that are akin to those of the golden ratio, in that

e^{-\Omega }=\Omega ,\,

or equivalently,

\ln(1/\Omega )=\Omega .

"

I'm not sure I can see any similarity to the golden ration here. Should this be obvious? :/ Woscafrench (talk) 01:00, 26 November 2007 (UTC)[reply]

One way to express the similarity in exact terms is as follows: if we replace f(x)=e^x with its linear approximation f(x)=x-1 then the solution to the equation f(x)=1/x would be golden ratio. Grue 15:36, 26 November 2007 (UTC)[reply]

I also doubt that sentence. No one can explain this better; it is just a point of view. I already removed it. --Octra Bond (talk) 02:29, 3 November 2009 (UTC)[reply]

The Omega constant to larger approximation?[edit]

I used Windows calculator to evaluate the Omega constant. The value of Omega is:

0.56714329040978387299

Interesting property of the Omega constant[edit]

Let k = 1/Ω, that is, the reciprocal of the Omega constant. Then it holds that:

{\frac {d}{dx}}k^{x}=k^{x-1}

That is, it imitates the power rule of derivatives (even though it's not a polynomial, but an exponential function with base k) in reducing the exponent by 1. The reciprocal Omega constant is the unique exponential base for which this is true.

Proof:

{\frac {d}{dx}}k^{x}={\frac {d}{dx}}e^{x\ln k}=(\ln k)(e^{x\ln k})=(\ln k)k^{x}

But since $e^{-\Omega }=\Omega$ , it follows that $e^{\Omega }=1/\Omega =k$ , and therefore $\ln k=\ln e^{\Omega }=\Omega =1/k$ . Substituting into the above equation, we have:

{\frac {d}{dx}}k^{x}=(\ln k)k^{x}=(1/k)k^{x}=k^{x-1}

as claimed.—69.172.154.75 (talk) 04:53, 27 September 2015 (UTC)[reply]

Question[edit]

I was asking myself if Ω is the the absolute value of the solution to

           $x+e x = 0$

I've found it with the approximative form thanks to the comparison between y=x and y=-e^x. If I'm not wrong, we can add it to the principal page. — Preceding unsigned comment added by 87.0.114.210 (talk) 14:35, 15 January 2017 (UTC)[reply]

Other property[edit]

(1/omega)^(1/omega)=e — Preceding unsigned comment added by 191.111.6.32 (talk) 22:07, 31 May 2022 (UTC)[reply]

Yes, but not surprising (ie pretty simple to deduce) and nor more snappy. Unless this is especially useful for something (best shown with a souce), I don't think it needs to be mentioned in the article.

I do think the continued fraction of omega would be more interesting. Xario (talk) 12:34, 2 December 2023 (UTC)[reply]

OEIS Sequences A370490 and A370491[edit]

OEIS Sequences A370490 and A370491 are the denominators and the numerators of an infinite series that converges to the Omega constant. Dacicus Geometricus (talk) 17:10, 6 April 2024 (UTC)[reply]
