I think i'm missing somethe here?

I guess I'm not holding my mouth right.

You don't use [tag], you use THE tags latex and /latex

Thanks I'll try one more time!

$f(x)=\int_{-\infty}^x\frac{(e^{-t^2})}{\sqrt{\pi^x}}dt$

Thanks: I think I've got it now.

A Feynman diagram, without the pretty wavy line...
$\setlength{\unitlength}{1mm} \begin{picture}(0, 0) \put(10, 20){ \makebox(3,0)[cc]{$\gamma$} \vector(1,0){10} } \put(24, 20){ \vector(2,1){10} } \put(24, 20){ \vector(2,-1){10} } \put(35, 25){ \makebox(3,0)[cc]{$e^-$} \vector(2,-1){10} } \put(35, 15){ \makebox(3,0)[cc]{$e^+$} \vector(2,1){10} } \put(50, 20){ \makebox(3,0)[cc]{$\gamma$} \vector(1,0){10} } \end{picture}$

please use the the math tags....

instead of [latex]-1=e^{\Pi i}[/latex]
$-1=e^{\pi i}$

use [math]-1=e^{\Pi i}[/math]
$-1=e^{\pi i}$

distinct advantages of the second over the first are:
you can now click on the expression to see the code
you can notice better rendering and space management
you can now do a load more with this then you were able to with latex... you can do stuff like this:
$I(z) = \sin( \frac{\pi}{2} z^2 ) \sum_{n=0}^\infty\frac{ (-1)^n \pi^{2n} }{1 \cdot 3\cdots (4n + 1) } z^{4n + 1}-\cos( \frac{\pi}{2} z^2 ) \sum_{n=0}^\infty\frac{ (-1)^n \pi^{2n + 1} }{1 \cdot 3\cdots (4n + 3) } z^{4n + 3}$

$\setlength{\unitlength}{1mm}\begin{picture}(60, 40){\put(30, 20){\vector(1, 0){30}}}{\put(30, 20){\vector(4, 1){20}}}{\put(30, 20){\vector(3, 1){25}}}{\put(30, 20){\vector(2, 1){30}}}{\put(30, 20){\vector(1, 2){10}}}\thicklines\put(30, 20){\vector(-4, 1){30}}\put(30, 20){\vector(-1, 4){5}}\thinlines\put(30, 20){\vector(-1, -1){5}}\put(30, 20){\vector(-1, -4){5}}\end{picture}$

i gotta go find if i can enable the pst-plot module.... that would be interesting
