Error in Special AIME Seminar A solution
fermat_sLastAMC   1
N Today at 4:22 AM by MathPerson12321
The text in the following image (of the solution for problem #3 of the practice AIME of 4134 Special AIME Seminar A) should state that the positions of A and B are plotted on the vertical and time is plotted on the horizontal.

Where should I post these kinds of errors in the future?

Contest collection PDFs don't work when LaTeX is embedded within BBCode
Equinox8   5
N Yesterday at 11:26 PM by jlacosta
This could very well be reported before, however a quick search did not find anything.

While embedding LaTeX commands within BBCode (like this: [i]text $\dfrac{1}{2}$ text[/i]) typically displays as intended within a forum, trying to render a contest collection using these commands breaks the PDF renderer.

As outlined in this (locked) post, the forum/blog creation message is out of date. It has been over a year since that post, and it still has not changed. I don't know if this got lost somewhere in the "passing this along" chain or if it was determined to be irrelevant, but it seems like a relatively simple fix ;)

k LaTeX sizing error?
ImSh95   22
N Aug 3, 2023 by jlacosta
Is this just me, or is the $4$ in $410$ bigger than the $4$ in $476$?

Summary of the problem:
Some numbers in $\LaTeX$ appear bigger than others.
Ex.: The font size of $11$ seems small compared to that of $53$.

Page URL: (none)

Steps to reproduce:
1. Type two dollar signs to begin writing in $\LaTeX$.
2. Type numbers in between the dollar signs.
3. Look at the preview. (This does not only occur in the preview. It occurs in posts as well.)


Expected behavior: Some numbers will appear to have a larger font size than others.

Frequency: 100%

Operating system: Windows 10

Browser: Mozilla Firefox 115.0.2 (64-bit)

Additional information:
My findings: (hidden for length)

I am aware that this might be just me. I'm also aware that this is not a big issue; I am just wondering why it's happening.

Thanks

All $\LaTeX$ expressions are cached, so the bigger and fuzzier looking images are likely due to an earlier version rendering it wonky, then that wonky version being saved and referenced forever. Note the same issue occurs with $\triangle ABC$ and $\triangle ABC~$. The former appears squished, while the latter renders like normal, although the only difference is a '~' at the end.

Also, in regards to your example at the beginning, I see the exact opposite.

It would be nice if AoPS could reset the cache, but that would lead to extreme lag as all $\LaTeX$ expressions are forced to re-render at the exact same time... Perhaps AoPS could reset the cache during a maintenance session?

This would also explain why asymptote is broken. Some weird things are cached in the memory, which explains the difference between
[asy]
dot((0,0));
[/asy]
and
[asy]
dot((0,0));[/asy]
Both of them have the exact same code, but the latter has one of the lines shifted.
Note: the former is too small to see, so I have attached an image of it.

I've noticed that a lot of the numbers have gotten weird recently:
$1$ $2$ $3$ $4$ $5$ $6$ $7$ $8$ $9$ $10$ $11$ $12$ $13$ $14$ $15$ $16$ $17$ $18$ $19$ $20$ $21$ $22$ $23$ $24$ $25$ $26$ $27$ $28$ $29$ $30$ $31$ $32$ $33$ $34$ $35$ $36$ $37$ $38$ $39$ $40$ $41$ $42$ $43$ $44$ $45$ $46$ $47$ $48$ $49$ $50$ $51$ $52$ $53$ $54$ $55$ $56$ $57$ $58$ $59$ $60$ $61$ $62$ $63$ $64$ $65$ $66$ $67$ $68$ $69$ $70$ $71$ $72$ $73$ $74$ $75$ $76$ $77$ $78$ $79$ $80$ $81$ $82$ $83$ $84$ $85$ $86$ $87$ $88$ $89$ $90$ $91$ $92$ $93$ $94$ $95$ $96$ $97$ $98$ $99$ $100$

This goes under this list of LaTeX issues:
List wrote:
This is known, but it is very difficult for developers to fix. It has been posted before and the developers are likely aware of it, but it is not high on the priority list.
Some examples include: $1~$ (vs $1$), $P$ (vs $P~$), $i$ (vs $i~$), $L$ (vs $L~$), $565$ (vs $565~$), $n$ (vs $n~$), $\triangle ABC$ (vs $\triangle$ $ABC$), and $10 \times 10$ (vs $10 \times 10~$).

There must have been a recent update, since there used to be issues with $2$, $3$, $5$, $9$, $3892$, and $1 \times n$.

imo i think its cuz the $1$ is less wide than the $7,$ so theres more space for the $4$ in $410$ than there is in $470,$ so i guess this is logical

That's a good theory, but I don't think it's the case. The numbers aren't all the same size, like $61$ and $66$.

Testing numbers with just dollar signs, dollar signs and ~, and dollar signs {} and ~. Seems like the {} and ~ have the nicest results.
$60$ $61$ $62$ $63$ $64$ $65$ $66$ $67$ $68$ $69$
$60~$ $61~$ $62~$ $63~$ $64~$ $65~$ $66~$ $67~$ $68~$ $69~$
$60{}~$ $61{}~$ $62{}~$ $63{}~$ $64{}~$ $65{}~$ $66{}~$ $67{}~$ $68{}~$ $69{}~$

$0$ $1$ $2$ $3$ $4$ $5$ $6$ $7$ $8$ $9$
$0$ $1~$ $2~$ $3~$ $4~$ $5~$ $6~$ $7~$ $8~$ $9~$
$0{}~$ $1{}~$ $2{}~$ $3{}~$ $4{}~$ $5{}~$ $6{}~$ $7{}~$ $8{}~$ $9{}~$

I typically use tildes (~), but $1~$ has been off for a while. It's still a pain since the LaTeX rendering also affects old posts and I don't want to use my time going through old posts to add tildes.
