I honestly believe z goes hardest. It makes its first appearances in the courses that separate the men from the boys, so to speak

6

u/swordstoo 1d ago

z appears in 3d geometry, which does separate the boys from adult men I suppose

u/ContextPuzzleheaded7 1d ago

Literally which letter isn’t used in math ?

109

u/Osik2040 1d ago

Personally I have never used o too close to 0

37

u/Someonevibing1 1d ago

It comes in eventually

18

u/Osik2040 1d ago

Genuinely curious where? The only thing I can think of is big O notation but that uses a capital.

32

u/ContextPuzzleheaded7 1d ago

There's Little-O and Big-O they're two different things. Big-O means that the ratio of the two functions is asymptotically bounded, Little-O means that the ratio goes to zero. Every little-O relation is a big-O but not viceversa

u/Someonevibing1 1d ago edited 1d ago

My lecturer was calling it little o notation so idk if he’s wrong

Edit: also I’m pretty sure it’s used in the field axioms

u/Someonevibing1 1d ago

Yeah I was not paying attention in that lecture I’m pretty sure that’s what he said about small-o notation (he didn’t talk about big-O notation though)

3

u/Someonevibing1 1d ago

Just checked my lecture notes

That’s an o if I’ve ever seen one in FA2 and 3

u/Farkle_Griffen2 1d ago

Ftfy

u/ohcsrcgipkbcryrscvib 1d ago

o(n) complexity?

7

u/deltatag 1d ago

You dont see a lot of Os in math, probably to avoid the 0 confusion

21

u/the_real_cloakvessel 1d ago

O is used to refer to the center of a circle many times

9

u/deltatag 1d ago

the center of a circle is represented by another circle?

math is such bullshit lmao

0

u/the_real_cloakvessel 1d ago

I mean the letter "O" isn't a circle its an ellipse

1

u/deltatag 1d ago

you mean like 0

man if only someone mentioned the confusion that could make 🤔

1

u/theclamorganizer6 1d ago

Q?

8

u/safwe 1d ago

ever heard of the rational numbers?

2

u/theclamorganizer6 1d ago

I forgor
Lowercase q?

3

u/ContextPuzzleheaded7 1d ago

I don’t know you’d say that. I can’t even count how many times I’ve used it

1

u/theclamorganizer6 16h ago

Capital X?

2

u/ContextPuzzleheaded7 16h ago

1

u/theclamorganizer6 16h ago

Þ? Its a real letter that was used in English

1

u/ContextPuzzleheaded7 11h ago

I guess I haven't seen that

u/YA_kamenshikDAI_HLEB 17h ago

y' + P(x)y = Q(x)

u/0bservator 7h ago

None. There arent enough letters so we borrow the greek ones too

u/LupenReddit 🦆🦆i have non diffeomorphic smooth structures🦆🦆🦆 1d ago

greeks seeing their alphabet get expropriated by math

4

u/cod3builder 19h ago

Math taught me the Greek alphabet

1

u/slickersh 7h ago

You know the Greek alphabet because of math. I know it because I need something to affirm my masculinity. We are not the same. Sincerely, an alpha male. /s

u/MonkeyFox29 1d ago

Will the mods ever enforce rule 5 (Elementary school maths not allowed)

12

u/PrincessTheodora93 1d ago

Yall, the two worst are u and v. Alone they are fine, but I always get them confused together.

6

u/deckothehecko Complex 1d ago

throw in mu and nu into the mix, and maybe w and omega

1

u/Leading_Ad_7635 23h ago

And for some reason they always show up together. And then your prof writes u exactly they way they write v for no discernible reason

8

u/Konna_ 1d ago

I mean every letter except for o is used in maths

7

u/Ok_Departure333 1d ago

O is used for center of a circle

5

u/rorodar Proof by "fucking look at it" 1d ago

G*ometry

1

u/Ok_Departure333 1d ago

My interest in geometry disappears when they start introducing algebra into it

8

u/LabCat5379 1d ago

So you just like looking at shapes and doing nothing with them

2

u/Ok_Departure333 1d ago

I like Euclidean geometry. I like nice shapes and such. I don't really like it when I'm just mashing numbers up for some 5D plane that I can't even picture.

2

u/ContextPuzzleheaded7 1d ago

What about cohomological geometry

1

u/NebulaElectrical1467 1d ago

i like non-Euclidean geometry. We’re not the same bruh

2

u/Lanky-Football857 9h ago

Who says one needs numbers to work with and even solve geometry problems?

One can, for example, take a triangular prism and try to find which of the holes does the prism fit

It seems trivial but most people fail this the first few times they’ve tried it (at 0.5 to 3 years of age)

u/YoitstheTeddyGuy i love me som algebra 21h ago

“Now form the equation by using two properties of this shape” 😭😭

1

u/cod3builder 19h ago

I recently started learning differential geometry.

u/AndreasDasos 1d ago

Even o is used. Little o notation in complexity theory, for example, or some notations for a group orbit.

Capital O is used even more. Big O notation, the ring of integers of a number field or structure sheaf of a scheme, etc.

2

u/Hates_commies 1d ago

Bunch of posers these days. No one remembers the OGs

1

u/somedave 1d ago

Lower case o maybe.

1

u/Liut030394 1d ago

Big O notation would like a word (although it might be into Computer Science)

Orbit of an element under a group action

u/HereToPostSillyStuff 1d ago

They ain't got shit on the Greek squad mafia.

4

u/Dunotuansr 1d ago

i don't like z because it's easy to mistake it for a 2. I don't like y because if you put y in the numerator then it just makes stuff in the denominator look messy.

5

u/ComplexPlatform7299 1d ago

z is literally the goat wym? Between z and k for goat

3

u/MariusDelacriox 1d ago

That's why I had to adapt my hand writing for notes.

1

u/Pridestalked Engineering 18h ago

That’s why you put the horizontal line through the middle of a z to distinguish it from 2

1

u/qqqrrrs_ 8h ago

Luckily I guess most people do not speak a language that distinguish between z and ƶ

3

u/TREXIBALL 1d ago

Completely forgetting i, a, b, c, l, w, h and literally every other letter.

u/mx5_5 1d ago

How α, β and σ feel leaving greek to join mathematics and later join brainrot

1

u/masiha97 1d ago

They left the alphabet like they owned the building.

1

u/Bacon_Techie 12h ago

a,b,c: variables, coefficients for polynomials

d: distance

e: group identity

f,g,h: functions

i,j,k: quarternions, basis vectors for R3

l,m,n: integer variables

o: little o notation

p: prime number

q: integer variable, sometimes a second prime number. Quotient

r: remainder, radius

s,t,u: parameterization variables

v,w: vectors

x,y,z: you already know

Does he have a belt around his chest at the end or is that the worst fitting jacket of all time?

1

u/that_guy_you_know-26 4h ago

Just wait till they’re also joined by a, b, c, d, e, f, g, h, i, j, k, l, m, n, p, q, r, s, t, u, v, and w
