# Quick LaTeX Tutorial

## Recommended Posts

Was thinking of writing a little math toolbar thing so that you can just click on the math symbols and the latex code would be inserted into the textbox.

I've also got a copy of the latest latexrender code, so I'll post that off to you soon with some instructions blike. I've managed to fix a few of the problems we have when quoting equations; the images produced are now transparent with a very minor reduction in quality from what we have atm, although it requires a little more CPU

how to install latex, it needed to put many file inside.

Would anyone upload the whole for me ?

Read the initial post: subscripts are generated by using _

For example, A_{n^2} produces: $A_{n^2}$

Dear Dave

I have tried numerous times to use the latex code for Matrix and Align equations. When I use the command for matrix I get:

$\begin{matrix} w & x \\ annoyed & z \end{matrix}$

and for align:

\begin{align} w & x \\ annoyed & z \end{align}

As you can see the ampersand persists. I have read a few 'latex' manuals and tried various code combinations. Could you or someone else be able to provide some information to overcome this problem.

The problem is that when you type the & into vB, it cleverly converts it into the html symbol for an ampersand; namely & which is why you're having problems. When I get back from holiday, I'll fix it; it's a fairly simple fix.

Thanks for highlighting the problem though.

Dear Dave

Thanks for the reply, I had a thought that might be the case.

Just thought I'd post this link http://www.ctan.org/tex-archive/info/symbols/comprehensive/symbols-a4.pdf. It's a relatively small, (approximately 2.3 MB) comprehensive set of symbol tables for $\LaTeX$ and some of its add ons.

The page I got it from is here: http://www.ctan.org/tex-archive/info/symbols/comprehensive/symbols-a4.pdf.

How would I write out something like $\sqrt{25} = 5$? How would I put the $5$ above the $\sqrt{25}$?

And what about aproximatly? How do you put that symbol in?

here is a really short guide. with most of the notation in there

Thank you.

Use \frac{5}{\sqrt{25}} - the first argument of \frac lets you specify the numerator, the second will give you the denominator.

Why isn't the latex working right now?

##### Share on other sites

I saw on the announcements that blike's upgraded some stuff. He probably forgot to put the latex code back in.

##### Share on other sites

What was he upgrading that he needed to take the LaTeX out?

It's been a while now and the  tags are still not working. What's going on?!

could someone please post all of the greek letters so no one has to guess at the abbreviation LaTeX uses?
