Hey all,

Just wanted to let you know I finished installing the code that enables LaTeX preview. Try it out and let me know if you find any bugs.

Geez, that must've been really hard to fix. :P

$$I = I_S (e^\frac{qV}{kT} -1)$$

Thanks chroot! That really is a big help in posting replies.

Since the recent update, I just noticed that my blog/journal entries with attempts at $$\LaTeX$$ now show graphic images... of the form "preview9587-0.png"... which are images from other LaTeX posts or previews of mine. They used to show the red "LaTeX image generation failed..." graphic. So, it seems that we are one step closer to LaTeX in the blog/journals... which might be a good place to place easier-to-find tutorials or notes... with no time limits on editing.. and no possible interference from other posters [but, of course, subject to approval by the mentors].

robphy,

I don't really have any intention of supporting LaTeX in blogs. What you're seeing is actually a bug: if the code is run inside anything other than a normal post, it assumes it's in a preview. That apparently wasn't a good plan...

Thanks Warren.

$$\nabla \times \mathbf{H} = \mathbf{J} + \frac{\partial \mathbf{D}} {\partial t}$$

$$\oint_C \mathbf{H} \cdot \mathrm{d}\mathbf{l} = \int_S \mathbf{J} \cdot \mathrm{d} \mathbf{A} + \int_S \frac{\partial\mathbf{D}}{\partial t} \cdot \mathrm{d} \mathbf{A}$$

Does this mean I can LaTeX all I want? How'd you get around the issues that were preventing you from doing it in the first place?

When couldn't you use LaTeX all you wanted?

I got around the issues by scouring the vB code for an hour or two and finding the right places to put my hooks. It was actually really easy to find a reasonable way to do it. I'm sorry I didn't do it a long time ago.

$$\chi\varpi\varpi\lambda$$.

$$\kappa oo\lambda$$ or$$\chi \omega\omega\lambda$$?

$$\varsigma o o \lambda$$

P.S. (yes, $\iota\tau$ works)
P.P.S. so does inline

Awesome, thanks!

LaTeX in previews is not working for me. Since no one else is reporting this problem, is it some setting on my browser (IE 8) I need to configure or something with the cookie I have do?
The following should look like the fraction 2/3 formatted nicely, but what I see when I preview it is an integral sign.
$$\frac{2}{3}$$

### Staff: Mentor

Now that I've posted it, the LaTeX code renders correctly, but it didn't in the preview.
Any ideas?

Mark, yes, LaTex doesn't always display properly in preview mode.

FYI:
