Seems to me there is a lot of "font size" etc in your code, I don't think that's supposed to be there.

Use the [math] tag, not the [latex] tag.

If you're pasting the code from somewhere, then you are getting font stuff from that program. Use notepad or something similar to clean up the code.

Testing grounds?

$Ke = \frac{1}{2} mv^2 = 0.5 mv^2$

$Ke = \frac{2}{2} mv^2 = 1 mv^2$

$Ke = \frac{3}{2} mv^2 = 1.5 mv^2$

$Ke = \frac{4}{2} mv^2 = 2 mv^2$

Just to look cool and show how little life i have:

$\setlength{\unitlength}{1mm} \begin{picture}(250,200) % This is merely for reference %\multiput(0, 0)(7.5, 0){5}{\line(0, 1){20}} %\multiput(0, 0)(0, 5){5}{\line(1, 0){30}} \thicklines \put(5.5, 5.5){\line(1, 5){2.2}} \put(11.5, 5.5){\line(1, 5){.85}} \put(13, 12){\line(1, 5){0.75}} \put(18, 6){\line(1, 5){1.75}} \put(22, 6){\line(1, 5){1.75}} \put(13, 12){\line(1, 0){4.5}} \put(12.5, 10){\line(1, 0){4.5}} \qbezier(17, 10)(19, 11)(17.5, 12) \qbezier(5.5, 5.5)(7.5, 3)(11, 5.5) \qbezier(18, 6)(19.5, 4.5)(21.5, 6) \qbezier(7.7, 16.5)(10.5, 18.5)(13, 15.5) \qbezier(19.5,14.9)(21, 17)(23.75,14.9) \end{picture}$

Note: revision two, now even cooler looking

Ok, couple of new things i have so far found with this version of latex:

\left now requires \right, this is sort of a bummer sometimes, i know, but get used to it... (yes that means that you have to provide a right delimiter as well, no it cant be empty for some reason)

in arrays, the next array space delimiter i.e going to the second c in {c c} is a single & (it will scream at a double with a random issue "Extra alignment tab has been changed to \cr")

By the way, you will notice that latex now shows you the error message, sometimes googling it is not a bad idea, or for a quick outline of the most common errors, have a quick glimpse at this page here: Common LaTeX Errors

Lastly you will notice that the [latex] tag no longer works at all, and i dont think we are bringing it back, though i should probably make it work like math tags, just so at least some of the formulas will show up :)

If, like me, you have some equally geeky mates, this equation editor ( Warning: this is a download, maybe check Ronan's website first) allows you to compose Latex equations and drag/drop them in compiled form into your mailer (or OpenOffice, for that matter).

Beauty of Ubuntu - just click and all the dependencies come too, all correctly assigned. If you already have tetex and/or livetex, nothing is corrupted, as far as I can tell. 38 files are automatically downloaded and installed, ~30min on my rig

Open with the command "eqe" in your terminal. I like it a lot.
