Oh... ok. I was looking at the /frac at the bottom of your post where it asks why it's not rendering. I didn't see the one at the top.

testing...
$\frac{1}{1}+\frac{1}{2}+\frac{1}{4}+\frac{1}{7}+\frac{1}{14}+\frac{1}{28} = 2$

$\frac{1}{1}+\frac{1}{2}+\frac{1}{4}+\frac{1}{7}+\frac{1}{14}+\frac{1}{28} = 2$

why is $/frac{1}{14}$ not rendering right using the latex tags instead of math tags?

I've noticed, though I have no explanation for this, latex tags need spaces where math tags do not. So I'm guessing...

$\frac{1}{1}+\frac{1}{2}+\frac{1}{4}+\frac{1}{7}+\frac{1}{14}+\frac{1}{28} = 2$

$\frac{1}{1}+\frac{1}{2}+\frac{1}{4}+\frac{1}{7}+ \frac{1}{14}+\frac{1}{28} = 2$

Yeah, a space before the "\frac{1}{14}" fixed it. To prevent it rendering you can use [noparse][/noparse] tags...

$\frac{1}{1}+\frac{1}{2}+\frac{1}{4}+\frac{1}{7}+ \frac{1}{14}+\frac{1}{28} = 2$

Sorry 'bout the confusion.

why are you guys using the latex tags???!!!???

DEAR PEOPLE!!!

It has come to my attention that you are still using the latex tags, even though they have been deprecated and outdated for quite some time now. I actually left the old engine on to support antiquated syntax in posts, but apparently some people STILL use it! Stop using the latex tags, they are deprecated and use far more resources then the math tags, simply because they don't do any caching!!!

I can only speak for myself, but I used them because I'm a noobus , and the title of the thread was Latex Practice Ground not Math Practice Ground. Do I take my shirt off, or leave it on for my lashes?

$u = \frac{v_1 + v_2}{1 + \frac{(v_1 \times v_2)}{c^2}}$

$u = \frac{v_1 + v_2}{1 + (v_1 * v_2)c^2}$

Well done Jones!
Another good tag to know is the multiply sign (it looks better than an asterisk).

$3\times4$
$3\times4$

or

$3\cdot4$
$3\cdot4$

I did notice one small thing,

\widetilde{abc} $\overwidetilde{abc}$
\widehat{abc} $\overwidehat{abc}$

A bit over wide But, really, all-around fantastic.

somebody messed with something in the plugin again, or someone played with the latex install, i gotta get to tormod, i noticed the ce tags were going crazy things too...

Let me find out what has changed, but something certainly did...

;$e=mc^2$

'Cause, on forums like ours, you don't tag it with \$...;, but $...$ or [imath]...[/imath].

So $e=mc^2$ renders as $e=mc^2$.

Was going to ask why the phrase you entered above wasn't rendered, but after seeing the quote I understand now.

$\frac{\dot{T}}{T} (\frac{\ddot{T}}{T} + \frac{kc^2}{a^2}) = \frac{8 \pi G}{3} \int\ [\dot{N} + N\dot{S}_k + N\dot{S}_{ik}] (\frac{8 \pi \hbar \nu^3}{c^3} \frac{1}{\frac{\hbar \nu}{k_BT} - 1} + \frac{8 \pi \hbar \nu^3}{2c^3})\ d\nu$
