I have been reading math in English for a while so I'm quite used to sentence constructions and commonly used expressions but I noticed that I still subvocalize formulas in my native language.
Part of it is because that's what I got used to hearing at my University for 5 years, part is that I simply do not know how to say those things since I never heard them (I mostly learned how to pronounce English from movies and tv series and they don't really do higher math in those often :)
For example to x=cos(x),x∈R.
X equals cosine of x, where x is from R? Element of R?
I am disabled, so I need it in textual form, for example 234/45 "234 over 45".
I can't watch videos or listen to audio.
A very nice explanation of all the symbolism in the movie.
Hi, I'm new to this sub. I've had a long history of odd dreams, but this one in particular felt worth sharing like this.
In my dream, I was in a room with my sister, looking at a sheet of paper with math problems on it. One of the symbols on it was something I felt familiar with in the dream, but never quite figured out how to use correctly, with only a vague memory of its function.
It was called an aquos, and it looked like this.

The regular form was the form on the left.
My memory of it was like this: it's essentially like the Pi symbol, indicating a very specific and important number. I think the reverse aquos indicates the reversed version of that number or something similar, and putting the two symbols next to each other indicates a function (which is why I'm not sure if the reverse aquos actually indicates the reverse version of the number, I think they would just cancel each other out in that case).
My sister opted to explain how it worked further, but I woke up before she could do so.
When I woke up, I was fairly sure it was real, but got confused as I realized I didn't recall when I'd seen it before. This only intensified once I looked over my keyboard and couldn't find it. It took around 3 minutes for me to internalize it's not real.
This was the final part of a dream that was otherwise unrelated to the aquos. The other part of it I remember was this:
I was in a room at school that usually functioned as the detention room, but I was there because I finished a big test early and had to leave the room and wait for everyone else to finish. The only other people in the room were the detention monitor and a boy that had a face like someone I'd seen back in middle school. He was quiet and reserved, seeming quite shy, but the monitor wouldn't leave him alone, chastising him for something I felt was petty that I can't quite remember (perhaps showing up a little late?). She then started outright making fun of him, and I lost my cool, shouting at her. This became an argument that devolved into a shouting match where we threw markers at each other. She would write down every insult I said on the room's whiteboard.
Throughout the course of this dream, I recall looking and feeling like I did when I was 15, which was the age I dropped out of public school. I'm currently 20.
I feel like this might be the wrong sub, but this is still a programming related question. A mathematical formula (https://www.sfu.ca/~ssurjano/bukin6.html) I'm trying to implement which contains | symbols which I don't really know how I'm supposed to implement or what I'm meant to do with it. I've tried to look online for what | could mean in mathematical terms but I can't seem to find an answer. If someone is able to help or direct me, it would be appreciated!
Is there a symbol for "guessing"? Or can we make one?
I've seen [?] = Guessed answered.
Let's guess that the answer is 52. Could this be written as [?]=52?
Thanks
Finally season 2 of 5-toubun aired. I couldn't help but notice the presence of several mathematical symbols. Actually, I had already seen the symbol of double integral in the title ( Gotoubun no hanayome ∬ ) but I thought it was there just for a stylish matter, but it looks like I was mistaken. In the opening we can see Fuutarou doing his homework (multivariable calculus), then we see Fuutarou and the bride approaching and the domain of integration appears. After that, the double integral appears. Would you attribute any meaning to this? Why did they choose to do this? As a first guess I would say (manga spoiler) >!5 is somehow connected to the 5 years passed since their first encounter!<
Here some pics.
(I think I'll expand more on this later).

I speak Farsi (and English :) ). In mathematics, when we are taking the double derivative of a function, we refer to it as "f zegond" which in English it would be something like " double derivative of function f".
At first I thought this word was introduced from French, but an online dictionary said it was taken from a German word with no reference to the actual word. I was hoping if you could tell me what this word was.
I think that the 'ze' part might be 'die' but that is just my guess with barely knowing anything in German.
I've found a couple references on the internet to a special-purpose typing tool probably brand-named "Type-It", though this could've been a jargon term in technical fields. Anyway, they appear to have been plastic sticks with a type slug on the end that were used for manually typing special characters such as mathematical symbols when using a typewriter that didn't have them. I'd love to get my hands on some of these, but I'm having no luck at all finding even pictures of them, or references other than these two accounts:
From https://dmrthesis.net/1960s-electronic-typing-technology/:
>In 1968 Brian Kernighan printed his doctoral thesis on an IBM 1403. As he describes it, “I did my thesis in the fall of 1968 at PU on IBM 1403 chain printers, which had no mechanism for subscripts or superscripts, so I was forced into notational contortions for the modest number of places where I needed them, and I did a handful of special characters with Type-its on a Selectric.”
From https://dmrthesis.net/1960s-typewriting-technology/
>“My father was a mathematician, and, before the IBM Selectric typewriter, I can tell you that he bought an expensive manual German typewriter along with boxes of these plastic sticks, each with a metal head containing a math symbol. Very slow and very painful.”
I have tried Google Cloud Vision, even though it predicts the text really well, it is failing at the math symbols and formula part understandably.
What I'm looking for is something that puts the meaning behind ancient analogies, such as
Living in the east Living in the right hemisphere of the brain
Lying down in the upper room/taking no thought Meditation/giving your mind to God
Temple body
Serpent spine, etc...
I'm new to my studies, but I have been traveling down a path that has been revealing itself to me more and more each day. I'm eager to continue learning, and continue heading to The Light. Until then, I'll just be hanging out in this beautifully furnished upper room ;)
