# Math Help - latex test

1. ## latex test

$x=7$

2. $\int_{-\infty}^{\infty}\frac{\cos ({x})}{({x^{2}+1})^{2}}=\frac{\pi}{e}$

3. Hi everyone,

Just testing how latex works in this new version!!

$x=55$

$\int_{a}^{b}~x~\sin{x}~dx$

4. Do we need math tags or do we use something else?

$y=mx+c$

$y=mx+c$

$y=mx+c$

5. $\forall$ doesn't work

$\exists$ doesn't work

$\because$ works!

$\therefore$ works!

$\mathbb{R}$, $\mathbb{Q}$, $\mathbb{Z}$, $\mathbb{C}$ work mostly...

It appears only a selected few commands work by themselves...but let's see if putting multiple commands in one tag works:

$\because\therefore$ doesn't work....

$\frac{a}{b}$ works

Too bad LaTeX is dysfunctional...its essential to keep this forum running.. xD

No LaTeX ? No math, eh ...

Lemme try : $\iiint_a^b 3 \sin{\left ( \frac{\log_3{(x)} + x}{3 \pi + \epsilon} \right )} + x \ dx$

I guess a triple definite integral involving two transcendental functions and a couple of greek letters is overkill xD

hmmm, mods any comment? Save us!

Issues to do with the current functionality of MHF are Admin issues, they cannot be resolved by the Moderators. I am confident these issues will get resolved in the fullness of time. Until then, patience is the order of the day.

$\iiint_a^b 3 \sin{\left ( \frac{\log_3{(x)} + x}{3 \pi + \epsilon} \right )} + x \ dx$

10. As a temporary solution to the problem with the formulas you can use the service from CodeCogs.com

To do this, we write this link http://codecogs.com/gif.latex? after the link write LaTeX-code formula and all this inside the tags [img][/img]

For example

[img]http://codecogs.com/gif.latex?y''+\frac{2y'^2}{1-y}=0[/img]

$y''+\frac{2y'^2}{1-y}=0$

[IMG]http://codecogs.com/gif.latex?\left\{\!\begin{gathered}0=0\cdot{a}+0\c dot{b}+c,\hfill\\30=30^2a+30b+c,\hfill\\40=60^2a+6 0b+c;\hfill\\\end{gathered}\right.~\Leftrightarrow ~\left\{\!\begin{gathered}a=-1/90,\hfill\\b=4/3,\hfill\\c=0.\hfill\\\end{gathered}\right.[/IMG]

$\left\{\!\begin{gathered}0=0\cdot{a}+0\cdot{b}+c,\hfill\\30=30^2a+30b+c,\hfill\\40=60^2a+60b+c;\hfill\\\end{gathered}\right.~\Leftrightarrow~\left\{\!\begin{gathered}a=-1/90,\hfill\\b=4/3,\hfill\\c=0.\hfill\\\end{gathered}\right.$

Warning: Do not put any spaces and line breaks within the code formulas!

Looks like these are working now.

That's a cool feature, didn't realise that was possible. I've been saving and uploading the images from that site as attachments, then posting the LaTeX code underneath. It's a bit tedious but has the advantage that if codecogs.com disappears, nothing needs to be changed.

13. Latex is working now.... including the double-click for source code.

test
$\displaystyle\oint_C f(x,y)dx+g(x,y)dy = \iint\limits_R\left(\frac{\partial g}{\partial x}-\frac{\partial f}{\partial y}\right)dA$

YAY!!! I works!!!

Thanks for the quick fix, MathGuru!

In principle, the administration can add a special BBcode in the engine of forum:

BBcode
