Great!! now we can write things like [tex]e^{i\pi}+1=0[/tex] and [tex]\sum_{i=1}^{n}x_i=\int_0^{1}f[/tex].

We need a few good links to online tex guides...

Excellent!

I've long wanted to be able to use [tex]\TeX[/tex] formatting.


Paul

There are several reasons why this took so long to get set up. The first reason is our old server didn't run Linux so a lot of software wasn't available. Secondly, we had very limited access to the server which prevented us from doing really cool stuff. We were also was hesitant to dive into a solution that didn't have a workable license. As it is, it pains us that the forum software itself isn't GPLed.

We have no idea how much of a load this will put on the server, but at any time we can redirect the image generation to another box running this. For now, especially if you are going to test some really crazy stuff, use the interactive editor thing.

Now that we have this set up, we realize we could have had this a long time ago, by redirecting the image generation to another box. We apologize that it took us this long to figure it out.

Who is going to post the most interesting example formula?

Have fun!

Just testing.

[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Could be bigger, don't you think?

[QUOTE=Numbers]Could be bigger, don't you think?[/QUOTE]
[tex]\LARGE \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]\displaystyle2\left(\frac12+\frac23\right)=\frac53[/tex]



Xyzzy, I think you're an absolute genius.
But you're going to have to tell me how to make it bigger, because even in displaystyle it still comes out pretty small.

[QUOTE=Numbers]But you're going to have to tell me how to make it bigger, because even in displaystyle it still comes out pretty small.[/QUOTE]Just hit "Quote" to see the source and you will see we added a \LARGE command. The documentation covers this. We have a sneaky feeling we could spend a lot of time learning all this. It seems to be very powerful. The interactive editor we linked to earlier makes it easier to try new stuff quickly.

[QUOTE=Numbers][tex]\displaystyle2\left(\frac12+\frac23\right)=\frac53[/tex][/QUOTE]

Big, or small, I don't like the math. :smile:
[tex]\LARGE\displaystyle2\left(\frac12+\frac23\right)=\frac73[/tex]

So there is more than one type of Latex?

[tex]\displaystyle{f(x)=f(a)+f'(a)x+\frac{1}{2}f''(a)x^2+\frac{1}{6}f'''(a)x^3+...}[/tex]

(I guess that answers my question. What I just typed would surely have worked on a certain other forum).

Often I use congruences, so I'll just pick a theorem at random...

[B]Theorem[/B]: Let [tex]p[/tex] be a prime such that [tex]p^2[/tex] divides [tex]M_q=2^q-1[/tex] for some prime [tex]q[/tex]. Then [tex]2^{\frac{p-1}{2}} \equiv 1 \pmod {p^2}[/tex] and so [tex]p[/tex] is a Wieferich prime.

[B]Proof[/B]: We know that if [tex]p[/tex] divides [tex]M_q=2^q-1[/tex], then [tex]p=2kq+1[/tex] for some [tex]k \in \mathbb{N}[/tex]. Then [tex]q=\frac{p-1}{2k}[/tex], and if [tex]p^2[/tex] divides [tex]M_q=2^q-1[/tex] then [tex]2^q \equiv 2^{\frac{p-1}{2k}} \equiv 1 \pmod {p^2}[/tex].

LaTeX available: Great !!!!!
 

Thanks Xyzzy !!!! :grin: :bow:
You even may do a little bit more: if you look at: [URL=http://www.physicsforums.com/showthread.php?t=85352]PhysicsForum[/URL] you can see that one can get the LaTeX source simply by clicking the LaTeX image. Can you provide the same on the Mersenne forum ?
Thanks again !
Tony

[QUOTE=T.Rex]Can you provide the same on the Mersenne forum ?[/QUOTE]How about if it pops up the source when you mouse over the image? Try it and let us know if this is what you are talking about.

LaTeX source pop-up: better
 

That's better since one no more has to click in "Quotes" in order to see the source. But it still does not enable to select the source code for pasting it in our own post without "Quot"ing.
Having a small window popping up with the source code seems to be more useful. What is the opinion of other users of the forum ? Can you build such a feature ?
Regards,
Tony

In both firefox and IE I can right click bring up properties and the source is there for me to copy.

Right Click ?
 

With Mozilla, right click doesn't provide any Copy.
With IEv6 under Wid, right click does provide a Copy but when I want to past, there is nothing to past (Past is in italic).
Will experiment on my native Windows-XP later.
Tony

[QUOTE=T.Rex]With Mozilla, right click doesn't provide any Copy.Tony[/QUOTE]

Right click on the LaTeX image, then select "Properties". This will bring up a window that contains the source in both "Alernate text:" and "Title: " which you can then select and copy and paste.

Dickman rho function:

[tex]\large \rho(\alpha) = \left{ \begin{array}{ll}0,&\alpha\leq 0\\1,&0<\alpha\leq 1\\1-\int_1^\alpha {\rho(t-1)\frac{\textrm{d} t}{t}},&1<\alpha\end{array}\right.[/tex]

Very, very nice. It doesn't know the cases environment, but a \begin{table}{ll} works just as well. Thanks Xyzzy!

Btw, I can't get the curly brace large enough. Is there anything bigger than Bigg?

You mean [b]\FrickinHuge[/b] didn't work? :no:

We have recompiled mimetex.cgi to enable caching, which should speed up the displaying of images a lot. Let us know if you all experience any problems.

Looks nice, but the text seems to be compressed, making it look a bit "messy".

a good link [tex]\tex[/tex]
 

[url]www.artofproblemsolving.com[/url]

is a good resource and has provided similar online [tex]\LaTeX[/tex] functionality for a while.

Sums should take care of their own size and placement of bound depending on their context

this sum should have bounds above and below because i used $$

[tex]$$\sum_{k=1}^N\varphi_kx_{N-k}<\infty \text{ for } (x_k) \in E$$[/tex]

whilst this one should have them inline because i didn't use $$

[tex]\underline{\bold{\Huge \sum_{k=1}^N\varphi_kx_{N-k}<\infty \text{ for } (x_k) \in E}}[/tex]

\textbf didn't work, maybe it's only in the ams packages... \bold works instead...

but $ and $$ are discouraged my many sources on [tex]\LaTeX[/tex] and are considered unsupported to say the least. they are equivalent to \( \) and \[ \] but these are not available here.

note: i don't mean to make a big deal of this, i use $ when i tex b/c my editor highlights them better but i would expect \( to work as well...
also is it possible to increase the default size?


yeah yeah i just registered and i'm already telling everyone what to do, so sue me :D

Does anyone know how to write the "Dell" symbol (the "upside-down" equilateral triangle that denotes the gradient)?

[ tex ] \nabla [ /tex ]

[tex]\nabla[/tex]

Hint: Search for "Gradient" in wikipedia :wink:

A couple cool tricks:

[tex]\today[2][/tex]


[tex]\calendar[/tex]

This one is just to see if the html linking works.


[html]
<img src=http://www.selectedplants.com/gardenphotos/sena.jpg>
[/html]

So it doesn't seem to pull this no matter how I modify the img string. Is it restricted to prevent attaching photos off of the net?

Fusion

Remote linking of images is dangerous because people can change the target down the road and inject in nasty pictures. It is much easier to just allow attachments.

(2^k)+1=prime????

k for 2=5

k for 4=17

k for 16=65537

k for 256=............

k for 65536=.............

k for 4294967296=...............

can it be?:help:

No.

2^256+1 has a factor 1238926361552897.

121645100409356287 is it a prime?

No:

121645 100409 356287 = 25561 x 4 759011 791767

Smaller numbers (<50 digits) can be easily tested with [url]http://www.alpertron.com.ar/ECM.HTM[/url]

thanks for your reply

Small ones can be checked in Linux.

[code]$ factor 121645100409356287
121645100409356287: 25561 4759011791767[/code]

Please test this....

Have anyone seen this: [url]https://sourceforge.net/projects/asciimathml/[/url] ?
It lets you type Tex formulas, and it parses it to MathML, so the server doesnt need to do anything, it would be cool to have it in the forum too :wink:

This is such a useful reference for teX anti-talents like myself - by making this thread [b]sticky[/b] it is easily referenced and available to newcomers.

Thanks in anticipation

We recompiled Mimetex today to take advantage of some new features. We have no idea what these features are, but you can read about them here:

[URL]http://www.forkosh.com/mimetexchangelog.html[/URL]

Our version was very old.

We've also enabled caching again.

Can someone help me up to render up this matrix on their PC please?

Vertical positioning
 

Would it be possible to vertically center the inline images of the TeX snippets? Compare [tex]\left(\frac{a}{p}\right)[/tex] with :smile:; the smilie fits nice.

We have attempted to adjust the style sheet to accommodate your request.

Most likely we have broken something critical somewhere.

Maybe if you see a whacked out math formula image let us know?

Did you add the '<span style="vertical-align: bottom;">' around those images? It looks the same to me in Chrome (5.0.375.70), but in Firefox (3.6.3) it does look good.

Something to do instead that works in both Chrome and Firefox (and should work anywhere) is to make it align like the smilies are made to align: use the "inlineimg" class to the img tag, which adds the "vertical-align: middle;" style.

In Firefox 3.0.6, the height of rendered TeX snippets now seems to get ignored, with the consequence that formulae with large height such as [tex]v = \left(\begin{array}1\\2\\3\\\end{array}\right)[/tex] overwrite adjacent lines. That change should be reverted.
In Safari 4.0.5, the renderings are bottom-aligned as before, and do not lose height information. Hence no visible change.

That's actually I think part of the "BSD games" package which is often found on Linux systems true enough. I suppose it is really found on more Linux systems than BSD systems by now. I suspect you could easily build it for ms-windows or apple too if you felt like it.

In its most common form it only supports native integers so the input is limited to 2 billion and some on 32 bit systems.

Subscripting seems to work, is there something you wanted to avoid here?

0 & \rightarrow_{j} & D & \rightarrow_{g} & E & \rightarrow_{r} & F & \rightarrow_{e} & 0\end{array}[/tex]

Why, the superscripting doesn't work for you??

[tex]\begin{array}{ccccccccc} 0 & \rightarrow^{i} & A & \rightarrow^{f} & B & \rightarrow^{etc}&C \end{array}[/tex]

(extended arrows use 2 parameters, if you replaced to normal arrow, the second one is not a parameter anymore, so you must use indexing, _ or ^ symbols)

Either would be fine. I copied it from the linked reference late in my editing because I was looking for something more graphical and I ran out of time. I'm not that TeX savvy and was just massaging the text that I copied to get rid of syntax errors. I have LyX and MiKTeX on my system but haven't been using them. I was also distracted by not wanting to use Category Theory words to talk about that entry because I didn't feel like being a dog trying to bark Greek. :geek: :raman: :razz:
