What's the correct interpretation this statement? "There exists a positive number 𝑥 such that for every positive number 𝑦, we have 𝑦²=𝑥." Is it ∃𝑥,∀𝑦[𝑦²=𝑥] or is it ∀𝑦,∃𝑥[𝑦²=𝑥] My (beginner) vote is for the first one ∃𝑥,∀𝑦[𝑦²=𝑥] #maths #quantifiers

Users from the #Netherlands - do you remember, or have you heard of, the mnemonic "Meneer Van Dalen Wacht Op Antwoord"? I have been googling for information about this but am looking for more sources, preferably original textbooks from the 20th century. I can find quite a few references to it but only *after* it was already phased out. Let me know if you remember, are interested and/or can help! I must confess up front I do not speak #dutch ! #nederland #wiskunde #math #maths #mathematics

"Before the introduction of the Arabic notation, multiplication was difficult, and the division even of integers called into play the highest mathematical faculties. Probably nothing in the modern world could have more astonished a Greek mathematician than to learn that, under the influence of compulsory education, the whole population of Western Europe [...] could perform the operation of division for the largest numbers." – Alfred North Whitehead (1861–1947) #quote #mathematics #math #maths

Can you colour the faces of a dodecahedron black and white so that if you stand on one of the faces you can determine your position and orientation by looking at your face and the adjacent faces? #math #maths #mathematics

What is your answer to 18÷3x2=? Boosts appreciated No, this isn't a trick question. An oft-cited blog has made the claim that "most humans" will get the wrong answer, which I think is a completely ridiculous claim, so I want hard data on the split. Unlike some other polls I've run, I want #teacher

Cannot get my head around transform.basis rotations. As always, language is a barrier. What is a "basis"? What grounding does it have? Is there any meaning? I used to be quite good at maths, but never enjoyed matrices. Does anyone have a selection of resources for how to understand? #godot #gamedev #maths

Hello – an #introduction. I’ve long been watching the fedi and now finally join. Commons: strong opinions i may not reflect, linux, love-hate computers, #trans, probably #autistic, cat owner (no pics), socially weird. Less-commons: studying #maths in #Prague (but mess into software too). A little bit into music and languages as well. Easily socially exhausted, thus sorry if i don’t respond to anything. Also have trouble w/ social expectations and often will just not interact. #Czech #Praha

1/x #MathsMonday I'm coming back to #Mathematics order of operations (hopefully) one last time, just to flesh it out with some more #Maths textbook references, for those who want it (having only initially given one in each case). Not going overboard, just 4 #Math textbook screenshots per post (since Mastodon only allows 4 pics per post, that's a good number to finish it off with). I may come back in future, if some particularly good ones come along, hence unknown post count for now...

what if... one could construct a low precision #MandelbrotSet orbit corresponding to a specific high precision orbit, without doing any high precision calculations?

I'm experimenting with constructing "tuned" periodic orbits by a simple algorithm (cycle one orbit, replacing the periodic 0 with successive values from a second orbit; scaled by Julia size of the first orbit, then iterate backwards with Newton's method to fix it up to be less approximate)

seems to work in some simple cases, in other cases the refinement pushes it to a wrong orbit*, so I think my initialization is wrong. plotting the images after each step of Newton refinement shows it takes some bonkers path instead of moving smoothly from the approximate to the accurate....

e.g. in attached video I specified to go to the same side relative to the mini each time, but it doesn't do that...

If an author writes a maths textbook with exercises, .... is someone else (me) allowed to write a book of solutions and publish it? Or does that break copyright? Or is reproducing the exercises considered "fair use" ? #maths #writing #publishing #copyright

X⇒Y is the same as "X is true only if Y is true" ... according to Tao Analysis I A.2. I still haven't settled this in my mind. It seems the wrong way around. Bur Tai says it takes some mental effort to see it. Is it obvious to you? How? #maths #logic

question about math notation Hover or focus to reveal Sensitive

This question doesn't lend itself well to plain text, so I LaTeX'd and screenshotted it. I'll do my best with the alt text. #math #maths #mathstodon #AskFedi

I've been taking some time to study some of the #mathematics that I learnt in high school and subsequently forgot, and I'm beginning to remember one of the big reasons I found the whole thing rather frustrating: so many #maths resources explain the techniques you can use to achieve certain results, but never bother to explain why these techniques work. It seems that I need proof that a given technique works before I can really trust it, and until then my brain refuses to accept it into the canon.

"The facts of mathematics are as useful as the facts of any other science. No matter how abstruse they may first seem, sooner or later they find their way back to practical applications. [...] The facts of today's mathematics are the springboard for the science of tomorrow." – Gian-Carlo Rota (1932-1999) #quote #mathematics #math #maths
