Latex is a typesetting system which allows you to generate simple to complex math equations that can't be created using normal text formats. You basically write your equation in the latex language and it translates it displays it correctly.

The language can get quite complex but the basics are easy. You can pick it up pretty quickly, so get stuck in!

Here are a few examples:

Example 1:

Code (text):
$\int$
TIP: Try clicking the math expression. It will popup a box showing you how it was created.

Example 2:

Code (text):
$\Large e^x=\lim_{n\to\infty} \left(1+\frac~xn\right)^n$
Example 2:

Code (text):
$\mathcal{F}_{x} [\sin(2\pi k_0 x)](k) = \int_{-\infty}^{\infty} e^{-2\pi ikx} \left( \frac{e^{2\pi ik_{0}x} - e^{-2\pi ik_{0}x}}{2i} \right) dx$

Electromaster, do you perhaps have a website you could refer us to where we can read about the specifics (limitations, syntax changes, etc) of this forum-oriented LaTeX module?

Just experimenting with a few simple formulae.

This isn't that difficult. I feel I'm comfortable with enough to get by and I'll still need to RTFM every now and the but it's easy when you know how. I'd rather use Latex than have to attach formula generated by Writer, it saves the copy and pasting.

testing import from Maple:
[ latex ]
F={\frac {kq_{{1}}q_{{2}}}{{r}^{2}}}
[ /latex ]

Yes it works!!

You should enter like this:
[ latex]F={\frac {kq_{{1}}q_{{2}}}{{r}^{2}}}[/latex]
[ latex]F={\frac {kq_{{1}}q_{{2}}}{{r}^{2}}}[/latex]

with no space in front of the word "latex"

You can actually get vb code to displaty by using [plain][/plain] tags, just wrap them around the code you want to display.

For example you can prevent codes from being converted to smilies.

[plain];) :D :o :) :( :confused: :mad: :p :rolleyes: :eek: [/plain]

/frac{/sqrt{2a^{2}b^{2}+2b^{2}c^{2}+2a^{2}c^{2}-a^{4}-b^{4}-c^{4}}}{4}

Please post a picture of the formula you want; use an easy to use program such as MS Equation for Word or OpenOffice Math.

I tried Hero999, but it would not upload. Anyways, sorry for the trouble.

Factorise:

(2 a square b square + 2 b square c square + 2 a square c square - a raised to the power of 4 - b raised to the power of 4 - c raised to the power of 4) / 16. The whole expression is under root.

Sorry, because the sum is in words.

For some reason the Latex on this form requires an variable/number followed by an equals sign.

For example, you can have:

or:

But you can't have:

or even something simple like:

I suppose a + b doesn't make much sense on its own.

I do not not understand what you express. However, that is beside the point. Could you please help my with me problem. I do not seem to get it.

I meant that Latex on this forum won't let you have:
a + b

you need to have:
c = a + b

This means that what you want to do won't work unless you have an = sign somewhere in-between some numbers or variables.

Like this?

Use curly brackets to surrond expressions, like y^2.
