In August of Japan, the method of cutting pizza and cake into equal areas as shown in the figure was popular on Twitter! It can be found at the following URLs:
(I was most inspired by https://twitter.com/potetoichiro .)
Recently I was taught the following two expressions formula,
From https://youtu.be/dO40DZk-qNU , I found https://www.wolframalpha.com/input/?i=(1%2Fx-5%2F(x%2Ba)%2B10%2F(x%2B2a)-10%2F(x%2B3a)%2B5%2F(x%2B4a)-1%2F(x%2B5a))*x*(x%2Ba)*(x%2B2a)*(x%2B3a)*(x%2B4a)*(x%2B5a)%3D(5!)+*+a%5E5 , Still I can't prove this proof yet.
It does not matter at all,
#ENWP "Tangential quadrilateral" https://en.wikipedia.org/wiki/Tangential_quadrilateral has an inscribed circle if only three sides (The fourth side must be \(a+b-c\) .) are decided (The shape is completely determined by the determination of another angle).
Thanks from https://twitter.com/takatasennsei !
Now I make PDF https://shinshu.us/itou.pdf , Thanks! We will plan to generalize Twitter "じゃがりきんａｐｕ長ピーポ黄金角形" https://twitter.com/wasanp_/status/1097612948007088128 in the future. #予定未定
@jsiehler I'm playing your #SlidingBlockPuzzles with so exciting! http://homepages.gac.edu/~jsiehler/games/Blocks-App/index.html (If I understand mechanism that one piece moving one time anyway is counted as 1-move, I may be able to reduce MOVES more!)
Now, I am interested in the following three.
1: "Sums of three cubes" https://en.wikipedia.org/wiki/Sums_of_three_cubes has generalized parametric representation "A New Method in the Problem of Three Cubes" https://arxiv.org/abs/1802.06776 (cf. ex. Old article in Japanese http://www.asahi-net.or.jp/~KC2H-MSM/mathland/math04/math0403.htm ).
2: DANIEL SCHER "A DOUBLE SPIRAL FROM DAVID HENDERSON" http://www.sineofthetimes.org/a-double-spiral-from-david-henderson/
3: Paul Bourke "Danzer Aperiodic Tiling" http://paulbourke.net/geometry/tilingplane/ telling by GirihApp@Twitter https://twitter.com/GirihApp/status/1106615831742558208 . I do similar one of the attached image
er, make that https://github.com/christianp/mastodon/commit/004c55beeb87e4f6af0ef690f20aed215e63b950 so autolatex.js is actually included

A fan of Tetris? This blog by Trupti from our archives introduces you to polyominoes! http://chalkdustmagazine.com/blog/polyominoes/
@no_TL And I found the image's duality. I'm very surprised because I didn't know this #ThankGod !
@no_TL In September, I was studying the "inverse geometry" https://en.wikipedia.org/wiki/Inversive_geometry of Japanese mathematics "Wasan" https://en.wikipedia.org/wiki/Japanese_mathematics. I thought the following image was the simplest and most beautiful result #現代和算
We've just released #Halcyon 2.4.4 with the following changes:
- Added a option to rewrite all #Birdsite links to a #Nitter instance which can be set by the instance admin
- Click on animated GIFs is now handled in the same way as normal images
- Enabling full height for images does now also work for animated GIFs
You can download it from https://notabug.org/halcyon-suite/halcyon/releases but please don't forget to add the new option in your config.ini
The Pokémon of the day is: Beedrill!
@no_TL And I'm testing the https://crossposter.masto.donte.com.br/ Thanks!
@no_TL #birdsite https://addons.mozilla.org/ja/firefox/addon/birdsite/ can tweet from #mastodon WebUI (visibility: "public" (& "unlisted" until v2.4?))! Well, I still can't CW etc…
@bremner One other thing -- in addition to .tex files we also support using .md (markdown) files with embedded latex. This can be useful for (collaborative) notes, since it's more friendly than full latex.
@bremner Thanks for you trying cocalc.com! Feel free to click Help button in cocalc in the upper right for any questions about course plans versus subscriptions or anything else, or if you just want to video chat with us.
I founded CoCalc to create a company that would be ideally aligned with heavily supporting open source math-related software development, and that is our ultimate goal.
