Adam, the definition of the lemniscates seems to vary. I've found sources on line that define the lemniscates with an escape radius, or with 1. I think we need to be clear whose definiition we are using, by giving a source for the information in the paragraph. From a mathematical point of view (as opposed to a computational one), I prefer 1, since we can define the mandelbrot set as the limit of the sequence of lemniscates with 1: there is no need to use any other threshold to define the set. By using the EscapeRadius, we will have a different sequence for each value of EscapeRadius. Not that there's anything wrong with that, simply that we don't need it. I'll try to find a good source for this today. Cheers,

Hi Adam. Just a note. There is no need to insert a <br> tag on Wikipedia. You can just hit "return" twice to go to a new paragraph.
And one more note, math notation should be in math tags, so <math>f(x)</math> instead of simply f(x). Cheers, Oleg Alexandrov ( talk) 02:19, 15 May 2007 (UTC)

Thanks for taking the time to change the internal link on the Arithmetic Dynamics page, but I'm going to revert back to the old version. Periodic and preperiodic points are not the same as Misiurewicz points. They don't live in the same spaces. For example, the Misiurewicz points for the polynomial x^2+c are the c-values for which the critical point x=0 is preperiodic. JosephSilverman ( talk) 15:54, 12 July 2009 (UTC)

Thanks for your question about File:Apollonian gasket.svg - yes, if you take all circles within the 20 levels/steps you get about 3^21 circles in all; but of course such a huge file couldn't be uploaded to commons and took a long time to render on a reasonably fast machine. Reducing the number of levels produced some ugly holes with no circles in at all, particularly around the edges where the three large circles touch the very large outer circle. Eventually I decided to modify the program so it would stop when it got to a certain radius of circle rather than going through a certain number of levels. I probably still have the code somewhere - let me know if you'd like to see it. Time3000 ( talk) 16:29, 4 September 2010 (UTC)
I removed the info about the decipherment using Arc, because (a) there doesn't seem to be anything very specific to Arc that makes this possible; (b) 30 people had done this before him without Arc, so what is special about this case?; (c) it doesn't seem to add anything useful to the Arc article.

Hi Adam, sorry for the delayed answer. Yes, I think there are two options: Either the title is changed to something like "Sand drawings (Vanuatu)" or maybe "Sandroings" or the article could be expanded to include similar practices around the world. From a long-term perspective, the latter option might be more attractive, I think. Cheers, Watasenia ( talk) —Preceding undated comment added 10:28, 20 November 2010 (UTC).

To clear it up:
For a function of one variable, y = y(x), only ordinary derivatives are needed.
To substitute values:
Since the derivative of a function (if it exists) is another function, some people also write:
then the derivative evaluated at a point x = a is written as for functions:
All this is Leibniz's notation. Newton's notation uses one dot over the y for each derivative with respect to x (this is especially used in the context of mechanics, when quantities are differentiated with respect to time). Lagrange's notation uses one prime on y for each derivative with respect to x.
For a function of more than one variable, f = f(x, y, z, ...), partial derivatives are used. A partial derivative with respect to any one variable follows exactly the same differentiation rules as for ordinary derivatives, just keep the other variables constant. For example if:
where p, q, r are constants, then:
Yet another notational convention is to use brackets and subscript the variables kept constant:
Hope this and the article on notation for differentiation helps. In case you have difficulties, please refer to a calculus text, the Schaum's Outlines books are really good (and affordable!). Best, M∧Ŝ c2ħε Иτlk 18:20, 14 January 2014 (UTC)

And i was trying to achieve a result like the image you posted. I have quite a different setup as what you use to render it, so i couldn't quite grasp my head around it.
Right now i can detect whether the point is inside the set using cabs(d) < eps. But from there, how can i color the points based on the distance?

Welcome to Wikipedia and thank you for your contributions. I am glad to see that you are discussing a topic. However, as a general rule, talk pages such as Talk:Möbius transformation are for discussion related to improving the article in specific ways based on reliable sources and the project policies and guidelines, not for general discussion about the topic or unrelated topics, or statements based on your thoughts or feelings. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages.

In this edit here, I reverted some information that appears to be a violation of our copyright policy.
I provided a brief summary of the problem in the edit summary, which should be visible just below my name. You can also click on the "view history" tab in the article to see the recent history of the article. This should be an edit with my name, and a parenthetical comment explaining why your edit was reverted. If that information is not sufficient to explain the situation, please ask.
I do occasionally make mistakes. We get hundreds of reports of potential copyright violations every week, and sometimes there are false positives, for a variety of reasons. (Perhaps the material was moved from another Wikipedia article, or the material was properly licensed but the license information was not obvious, or the material is in the public domain but I didn't realize it was public domain, and there can be other situations generating a report to our Copy Patrol tool that turn out not to be actual copyright violations.) If you think my edit was mistaken, please politely let me know and I will investigate. S Philbrick (Talk) 12:28, 17 July 2021 (UTC)

For a function of more than one variable, f = f(x, y, z, ...), partial derivatives are used. A partial derivative with respect to any one variable follows exactly the same differentiation rules as for ordinary derivatives, just keep the other variables constant. For example if:
where p, q, r are constants, then:
Yet another notational convention is to use brackets and subscript the variables kept constant:
Hope this and the article on notation for differentiation helps. In case you have difficulties, please refer to a calculus text, the Schaum's Outlines books are really good (and affordable!). Best, M∧Ŝ c2ħε Иτlk 18:20, 14 January 2014 (UTC)

Hey there, I saw your image on a wikibook https://commons.wikimedia.org/wiki/File:Mandelbrot_set_with_Interior_detection_method.png
And i was trying to achieve a result like the image you posted. I have quite a different setup as what you use to render it, so i couldn't quite grasp my head around it.
Right now i can detect whether the point is inside the set using cabs(d) < eps. But from there, how can i color the points based on the distance?

Welcome to Wikipedia and thank you for your contributions. I am glad to see that you are discussing a topic. However, as a general rule, talk pages such as Talk:Möbius transformation are for discussion related to improving the article in specific ways based on reliable sources and the project policies and guidelines, not for general discussion about the topic or unrelated topics, or statements based on your thoughts or feelings. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages. Thank you. – Deacon Vorbis ( carbon • videos) 15:14, 14 June 2020 (UTC)
In this edit here, I reverted some information that appears to be a violation of our copyright policy.
I provided a brief summary of the problem in the edit summary, which should be visible just below my name. You can also click on the "view history" tab in the article to see the recent history of the article. This should be an edit with my name, and a parenthetical comment explaining why your edit was reverted. If that information is not sufficient to explain the situation, please ask.
I do occasionally make mistakes. We get hundreds of reports of potential copyright violations every week, and sometimes there are false positives, for a variety of reasons. (Perhaps the material was moved from another Wikipedia article, or the material was properly licensed but the license information was not obvious, or the material is in the public domain but I didn't realize it was public domain, and there can be other situations generating a report to our Copy Patrol tool that turn out not to be actual copyright violations.) If you think my edit was mistaken, please politely let me know and I will investigate. S Philbrick (Talk) 12:28, 17 July 2021 (UTC)

Thank you for
your contributions to Wikipedia. It appears that you copied or moved text from
User interface into another page. While you are welcome to re-use Wikipedia's content, here or elsewhere,
Wikipedia's licensing does require that you provide attribution to the original contributor(s). When copying within Wikipedia, this is supplied at minimum in an
edit summary at the page into which you've copied content, disclosing the copying and
linking to the copied page, e.g., copied content from [[page name]]; see that page's history for attribution
. It is good practice, especially if copying is extensive, to also place a properly formatted {{
copied}} template on the talk pages of the source and destination. Please provide attribution for this duplication if it has not already been supplied by another editor, and if you have copied material between pages before, even if it was a long time ago, you should provide attribution for that also. You can read more about the procedure and the reasons at
Wikipedia:Copying within Wikipedia. Thank you.
I have removed the copied text as it was unsourced and largely incorrect. PaulT2022 ( talk) 21:53, 2 December 2022 (UTC)
