Latex is a high-quality system to generate complex math algarithymes that cant be created using normal text formats.

The best way to explain is by showing you.

Example 1:

Code:

[ latex ] \int [ /latex ]

Code:

Example 2:

Code:

[ latex ] \Large e^x=\lim_{n\to\infty} \left(1+\frac~xn\right)^n [ /latex ]

Code:

Wow this looks cool but it is a little is tricky!

Let's start with something a bit more simple first.

Like how would I do ohms law, what about I = V/R?

I've given it a go but it doesn't work.

$I = \frac~VR$

How do I get rid of that x?

Alright, I'll rtfm, I'll look at thoush liks you've posted.

**ElectroMaster** · 27th September 2006, 12:23 AM

Yes it is very advanced stuff but its quite fun to learn.

evandude · 28th September 2006, 06:01 PM

yeah, that 'x=' at the beginning doesn't make much sense. It also doesn't appear to have support for text/multiple equations/etc, ie - it seems to be only for formatting a single equation, which is the important part, but I am guessing the rogue 'x=' has something to do with that... (because it's not something that happens in "normal" latex)

Take, for instance:

Code:

Let ( f ) be the function defined by ( f(x) = 3x + 7 ).

taken from the LaTeX primer at:
http://www.maths.tcd.ie/~dwilkins/La.../MathMode.html

and it results in:
$Let ( f ) be the function defined by ( f(x) = 3x + 7 ).$

rather than the result you see on that webpage.

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?

Hero999 · 28th September 2006, 06:37 PM

You're right, I don't know where that x is comming from.

$f(x) = 2x + \frac{x - 7}{x^2 + 4}]$

**ElectroMaster** · 28th September 2006, 08:15 PM

sorry guys. Thats my bad!

I will edit the config!

Hero999 · 8th October 2006, 05:25 PM

Just experimenting with a few simple formulae.

$X_C= \frac{1}{2 \pi FC}\$

$Z = \sqrt{X_C + R}$

$R2 = R1 \frac{V_{OUT}-V_{REF}}{R1 \times I_{ADJ} + V_{REF} }\$

$V_{OUT} = V_{REF} \left(1+ \frac{R1}{R2}\ \right)+I_{ADJ} \times R2$

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 ]

$F={\frac {kq_{{1}}q_{{2}}}{{r}^{2}}}$

bananasiong · 18th October 2006, 04:51 PM

Testing:

$\large I=\ \frac~VR$

$\large f=\ \frac~1{2\pi \sqrt {LC}\ }\$

bloody-orc · 18th October 2006, 07:21 PM

what is wrong with my latex commands? sometimes they work but sometimes they dont (my pervious post)

Yes it works!!
$F={\frac {kq_{{1}}q_{{2}}}{{r}^{2}}}$
$<br /> F={\frac {kq_{{1}}q_{{2}}}{{r}^{2}}}<br />$

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

with no space in front of the word "latex"

bloody-orc · 20th October 2006, 09:14 AM

haha! got it. i had the latex statements before and after the code but they were on sepperate lines than the code itself (like when writing quotes etc...

was like this:
[lateks]
code
[/lateks]

Hero999 · 20th October 2006, 08:45 PM

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

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

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

Stronghold_2 · 10th March 2007, 12:10 PM

I have been troubled by this factorisation sum for quite some time now. Please help me.

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

Hero999 · 10th March 2007, 12:42 PM

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