Why do you write things like {{f}_{n}} in TeX instead of just f_n? Or \underset{n\to\infty}{\mathop{\lim}} instead of \lim_{n\to\infty} ? \lim is already a standard operator name, and when it appears in a "displayed" as opposed to "inline" setting, its subscripts appear directly below it, without the need to use "underset". (Similarly with \sup.) Is there some account of TeX on the web somewhere that says things should be done that way? Michael Hardy (talk) 06:51, 20 February 2012 (UTC)

Actually, I am using Mathtype which automatically produces these kinds of things. Guess I'll have to learn Tex ! Oldtimermath (talk) 23:31, 20 February 2012 (UTC)

I'm too old to learn TeX. Have to stick with MathType. Sorry.Oldtimermath (talk) 23:31, 16 June 2016 (UTC)

With regard to the unidentified editor's comments, I guess I am psychotic. Sorry about that. Oldtimermath (talk) 04:30, 6 July 2016 (UTC)

Speedy deletion nomination of File:Topographical (moduli) image of an infinite composition of complex functions.jpg


A tag has been placed on File:Topographical (moduli) image of an infinite composition of complex functions.jpg requesting that it be speedily deleted from Wikipedia. This has been done under section F1 of the criteria for speedy deletion, because the image is an unused redundant copy (all pixels the same or scaled down) of an image in the same file format, which is on Wikipedia (not on Commons), and all inward links have been updated.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be removed without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines.

Hi. Thx for the interesting image. Can you add Basic source code, categories and more description ? TIA --Adam majewski (talk) 17:52, 16 March 2018 (UTC)

Adam, Those images were created using BASIC programs I have written over the years. For each point in a region of the complex plane the programs perform compositions as I have described and evaluate the modulus or absolute value of the process, then paint that pixel a color shade, usually black and red for values near zero, going up to green, then light blue for large values.
