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

Thanks Tormod I think it will take me a while to get used to the math or latex syntax, but thanks for helping, its much appreciated.

Testing grounds?

[math]Ke = \frac{1}{2} mv^2 = 0.5 mv^2[/math]

[math]Ke = \frac{2}{2} mv^2 = 1 mv^2 [/math]

[math]Ke = \frac{3}{2} mv^2 = 1.5 mv^2 [/math]

[math]Ke = \frac{4}{2} mv^2 = 2 mv^2[/math]

There is a link to practice ground in the initial post, arkain :)

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

[math]
\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}
[/math]

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 [math] 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.

example of aligning equations from the other tutorial, just so they are almost redundant:

[math]\begin{split}E^2-(pc)^2&=(m_0c^2)^2\\E^2&=(m_0c^2)^2+(pc)^2\\E&=\sqrt{(m_0c^2)^2+(pc)^2}\\E&=c\times\sqrt{(m_0c)^2+p^2}\\\text{where } p=\gamma m_0v\\E&=c\times\sqrt{m_0^2c^2+\gamma ^2m_0^2v^2}\\E&=m_0c\times\sqrt{c^2+\gamma v^2}\end{split}[/math]
