Does anybody know of any programmes for writing latex (and are also free )

Thanks in advance,

Just learn LaTeX...it's not a difficult language to learn....

is rendered with the code:

CODE

[display]s=ut+\frac {1}{2}at^2[/display]

And there are plenty of tutorials out there, and a good enough explanation in the Maths thread here!

Just testing that Ive used that program properly. Obviously not.

[display]s = ut + 1/2at^2[\display]

[The Wedge Effect]

Meh, I prefer to actualy code it myself, less confusing and time consuming.

CODE

[display]\sigma _x^2  = \frac{1}{n}\left\{ {\sum\limits_{i = 1}^n {X_i^2  - n\overline X ^2 } } \right\}[/display]

Statistical variance formula, just using that as a test to see if this program is any good.

(rendered with the program for testing)

Edit: It works! Just get rid of the gibberish, and you only need to use the bottom line in that equation, where you can actually see the equation itself, enclose it between the [tex] or [display] tabs, and of course, get rid of all gibberish before and after those square brackets, and the square brackets themselves, it should come out fine.]

Most of the time, I do just type latex from memory (for thing like factions and powers, it's really easy).

However, if I'm doing something with lots of lines, trig functions, fractions within fractions, and so on, I'll tend to use texaide.

\[s = ut + 1/2at\^2\]

The lines with % are just comments (basically if you copy it and paste it into texaide/mathtype again, you can edit it.

To get it to work properly: delete the comment; replace the \[ with [tex] or [display], and the \] with the matching closing tag.



That looks a little bit wonky - are you sure it looked ok in texaide?

[The Wedge Effect]

I think he just simply typed s=ut+1/2at^2 and assumed it'd come out the way I produced it earlier.

Anyway this program is great for complicated expressions! I'll be using this program more!

[Nathan]

did it work?

edit: n and r should be like

n
r

and not nr...any ideas on how to fix this?

[Nathan]

ah...thanks

[Dave]

its just using the matrix functions in the program

[Nathan]

its just using the matrix functions in the program

i see....i was using brackets instead

[George]

Latex also has a built in command for "n choose r", as shown below:

CODE

[display]{n \choose r} = \frac{n!}{r!(n-r)!}[/display]

[The Wedge Effect]

Hmm, cool, didn't know that.

[Joel]

Well, I started teaching myself latex a couple of days ago. I've made a few things that might be useful for higher maths, if anyone wants to use them as templates then please go ahead.

Synthetic Division:

CODE

[tex]\begin{tabular}{rc|ccccl}
\footnotesize{(x - 2)} = 0 & 2 & 3 & 2 & 1 & 4 \\
\footnotesize{x = 2} & & \downarrow & 6 & 16 & 34 \\
\cline{3-6}
\multicolumn{2}{c}{} & 3 & 8 & 17 & 38 & \!\footnotesize{r = 38 so (x - 2) is not a factor.} \\
\end{tabular}
[/tex]

Nature Table:

CODE

[tex]\begin{tabular}{c|ccccc}
\!x\! & \!\!\rightarrow & \!\!\!\!-1 & \!\!\!\!\rightarrow & \!\!\!\!6 & \!\!\!\!\!\rightarrow\!\! \\
\hline
\!x \!+ \!1\! & \!\!- & \!\!\!\!0 & \!\!\!\!+ & \!\!\!\!+ & \!\!\!\!\!+\!\! \\
\!x - 6\! & \!\!- & \!\!\!\!- & \!\!\!\!- & \!\!\!\!0 & \!\!\!\!\!+\!\! \\
\hline
\!f'(x)\! & \!\!+ & \!\!\!\!0 & \!\!\!\!- & \!\!\!\!0 & \!\!\!\!\!+\!\! \\
\hline
\!\footnotesize{shape}\! & \!\!\mathinner{\mkern2mu\raise-1pt\hbox{.}\mkern2mu\raise2pt\hbox{.}\mkern2mu\raise5pt\hbox{.}\mkern1mu} & \!\!\!\!\!\!\mathinner{\mkern2mu\raise5pt\hbox{.}\, \mkern2mu\raise5pt\hbox{.}\, \mkern2mu\raise5pt\hbox{.}\mkern1mu} & \!\!\!\!\!\!\mathinner{\mkern2mu\raise5pt\hbox{.}\mkern2mu\raise2pt\hbox{.}\mkern2mu\raise-1pt\hbox{.}\mkern1mu} & \!\!\!\!\!\!\mathinner{\mkern2mu\raise-1pt\hbox{.}\, \mkern2mu\raise-1pt\hbox{.}\, \mkern2mu\raise-1pt\hbox{.}\mkern1mu} & \!\!\!\!\!\!\mathinner{\mkern2mu\raise-1pt\hbox{.}\mkern2mu\raise2pt\hbox{.}\mkern2mu\raise5pt\hbox{.}\mkern1mu}  
\end{tabular}
[/tex]

The nature table started to get complicated when I added the shape of the curve, and I couldn't manage to get f'(x) to appear properly (doesn't seem to work when it is put in a table). I'm also working on a CAST diagram, if anyone would find that useful then please let me know.

Edit: Okay, I've added code for both. I know the code for the nature table looks a mess, I'm still trying to find an easier and better way to do it. Obviously Latex wasn't designed for drawing nature tables...

[Ally]

Looks good!

[Joel]

Looks good!

Cheers.

Can you put the code for those under them, in between the [code] tags? It'd help if people wanted to copy and paste the code to edit for their own use.
