Is Mandatory LaTeX Implementation on PF Beneficial for Members?

Hah! Missing terminator

The third Pauli matrix is

$$/sigma_{3} = \left(\begin{array}{cc}1&0\\0&-1\end{array}\right}$$

I think you forgot a [ /tex]:

Once more

Huh, That stuff before wasn't what I entered. Let's see if this one works
$$g_{c}(A^{k}) = k_{s(e)}^{-1}g_{e}(A)k_{t(e)}$$

Okay! Wahooo!

 

[ahrkron]

$$\begin{array}{| c | c |}1&0\\0&-1\end{array}$$

$$\begin{array} {| c | c |}\hline 1&0\\ \hline 0&-1\\ \hline \end{array}$$

 

[ahrkron]

$$\phi$$

$${\color{red} \phi}$$

$${\it Let \phi denote the angle between ...}$$

 

[ahrkron]

$$\begin{array}{|c|c|}1&0\\0&-1\end{array}$$

uh...i am not sure what i am supposed to do?

Nooo!

$$what^{\it sort}_{\it of}crazy^{\it stuff}_{\it is}this?$$

 

[Phobos]

$$well_k^o then$$

This is going to take some practice.

 

[Kerrie]

i am unsure of how to use the latex script?

 

[ahrkron]

You basically just type some latex code between [ tex] and [ /tex].

It allows math symbols and notation to be displayed neatly. You just need to learn how to code in tex:

"\alpha" results in $$\alpha$$
"g_{\mu \nu} --> $$g_{\mu \nu}$$

It will be a BIG plus for the science forums at PF.

More trials:

$$\begin{array}{| c | c |}1&0\\0&-1\end{array}$$

 

[ahrkron]

I'm getting the impresion that, if I get the message "Latex graphic is being generated, reload in a moment" the very first time I submit, the graphic never gets to be there... can that be the case?

There are a couple posts I made last night that are still in that state.

Improperly aligned tensor indices:

Trying spacers:

$$Great_{\it I\ was}{}^{\it wondering}{}_{\it how~to~do}{}^{\it that!}$$

Non-italicized super/subscripts:

$$v^{\rm top}$$, $$v_{\rm bottom}$$

So when are we letting this go mainstream?

For light-gray post backgrounds, the TeX images look okay, but their borders don't look so good against the posts with dark-gray backgrounds. Is there any way to get it to antialias to different background colors depending on which post it's in?

It might be nice to supplement the default installation with some extra packages and fonts, like amsmath (amsfonts, amssymb), wasysym, marvosym, etc. Maybe we could even add some forum-specific user-defined macros of our own.

This kind of bugs me too -- but there's no way to determine exactly what background color to antialias to. I think the best solution to it might actually be to change the default color scheme for the site -- but I don't know what to do about that yet. It would look a little prettier if the antialiasing were exactly correct, I know.

amsmath, amsfonts, and amssymb are already included -- give 'em a try. As far as the others, sure -- we can add them. Let me know.

Ambi, you're still having the problem where new replies not working, but edits working? Hold on just a sec...

Maybe overzealous on the search-and-replace on those x's, eh?

Okay.. new replies should work. The post preview and topic reviews now show a better message:

LaTeX image not viewable here.

This should mean the end of the dreaded "LaTeX image being generated." message.
