Title: LaTeX tutorial
Post by: joshuamorgan on December 09, 2007, 04:21:53 pm: I've come to know LaTeX somewhat intimately over the past year - I've been typesetting some of my Methods assignments and notes using it (my handwriting is terrible!). Here are some of the things I commonly used, feel free to contribute more. A list of LaTeX mathematical symbols is available at http://amath.colorado.edu/documentation/LaTeX/Symbols.pdf.

Fractions

\frac{4}{5}
$\frac{4}{5}$

Trigonometric Functions

\sin x $\sin x$

Code: [Select]

Code: [Select]
\tan x $\tan x$

Logarithms and Indices

Code: [Select]
\log_{2} 6 $\log_{2} 6$

Code: [Select]
10^{20} $10^{20}$

Code: [Select]

My handwriting's bad too :P
I used to use the equation editor in OpenOffice for formatting equations :D

I used to use MathType when I used Microsoft Office, but IMO the equation editor in OpenOffice is better :)

It is.

Code: [Select]
[tex]\mbox{Hello world}[/tex] $\mbox{Hello world}$

Post by: phagist_ on December 24, 2007, 01:42:15 pm: Could you possibly make it that so when you click on the generated text it gives you the source code?
i.e see here

Cheers :)
Title: Re: LaTeX tutorial
Post by: Daniel15 on December 24, 2007, 09:23:03 pm: phagist_, I'll see what I can do :)
For now, you can click the "Quote" link next to a post and then look in the quote for the code. Or, right-click the image and view its properties, the LaTeX expression will be present in the URL, after the ?

For example:
$\mbox{Hello world}$
http: //stuff.daniel15.com/cgi-bin/mathtex.cgi?%5Cmbox{Hello%20world}

By using the "tex" BBCode:

Code: [Select]
[tex](x+2)^5 = 7[/tex]
$(x+2)^5 = 7$

Post by: /0 on January 13, 2008, 05:07:23 pm: Test...test

Code: [Select]
\begin{vmatrix} a & b & c \\ d & e & f \\ g & h & i \end{vmatrix}
$\begin{vmatrix} a & b & c \\<br />d & e & f \\<br />g & h & i \end{vmatrix}$

Code: [Select]
\begin{pmatrix} \Alpha & \Beta & \Gamma & \Delta \\ \Epsilon & \Zeta & \Eta & \Theta \end{pmatrix}
$\begin{pmatrix} \Alpha & \Beta & \Gamma & \Delta \\ <br />\Epsilon & \Zeta & \Eta & \Theta \end{pmatrix}$

Code: [Select]
\overbrace{Hello\ World}^{Heaven} \equiv \underbrace{Hello\ World}_{Heck}
$\overbrace{Hello\ World}^{Heaven} \equiv \underbrace{Hello\ World}_{Heck}$

Hey how come my second one doesn't work??
Title: Re: LaTeX tutorial
Post by: Collin Li on January 13, 2008, 05:34:52 pm: Your second one works if you replace it with the lower-case versions. I'm not sure why some of the upper-case ones are missing.

$\begin{pmatrix} \alpha & \beta & \gamma & \delta \\<br />\epsilon & \zeta & \eta & \theta \end{pmatrix}$

Title: Re: LaTeX tutorial
Post by: Collin Li on January 13, 2008, 08:07:50 pm: Use modify instead of double posting please.

You have to write them in BBCode tags.

Code: [Select]
[tex]Insert code here[/tex]
Just like how
Code: [Select]
[b]Bold text[/b] gives you: Bold text

Post by: mozart on January 13, 2008, 08:13:32 pm: oh yer sorry about that,.

is there a code button somewhere?
Title: Re: LaTeX tutorial
Post by: Collin Li on January 13, 2008, 08:16:26 pm: Huh?

No, I don't think there is a button for it, you just have to type out manually:

Code: [Select]
[tex]\mbox{Some sample code here: }\alpha \beta \leq \frac{x}{y}[/tex]
Produces this:
$\mbox{Some sample code here: }\alpha \beta \leq \frac{x}{y}$

If you're really confused, quote my post and have a look at how it's written out, and you should be able to work it out.

That's a bit big, it needs to be 23x22 (like all the normal buttons)
Don't worry, I'll try to find something to use :D

23x22 :D

and if you want the png version
Title: Re: LaTeX tutorial
Post by: Daniel15 on January 14, 2008, 05:36:52 pm: I tried making that GIF so it has a transparent background (which is what's needed for the BBCode buttons), but it didn't turn out so well. Oh well, at least there's a working button now :D

Edit: fixed it, looks a lot nicer now :)
Title: Re: LaTeX tutorial
Post by: Mao on January 14, 2008, 07:28:15 pm: lol i made the png so it was fully transparent! xD

oh well, that's cool

looks good daniel :D

Post by: Daniel15 on January 14, 2008, 07:45:58 pm: SMF requires transparent gifs, though ;)

sorry i was lazy :P
