Only some of the logic notation appears to work:

All rendering okay:

Not rendering:
[LaTeX Error: Syntax error], [LaTeX Error: Syntax error].

\and and \or aren't symbols in LaTeX. You can use \wedge and \vee though.

Strange, they appear on the Wikipedia LaTeX guide - maybe they are using an obscure package.

[Cap'n Refsmmat]

I think Wikipedia uses a bunch of the AMS packages by default. I could add some to our package list if you find out what we need.

One thing that hasn’t been mentioned in this thread so far is formatting colors in LaTeX.

In that case you might want to use \mbox around plain text such as 'if', and use the \cases notation rather than trying to hack your way around a matrix.



See how that looks neater both in terms of code and output?

Why doesn't the factorial sign work in LaTex here? for example, works, but when I use factorial sign after the '2' in the denominator, I get an error message:

Should be fixed now. It was a bug in how the software handled exclamation marks -- I didn't realize IPB escapes them to their HTML entities.

Pardon the interuption, but I was trying to use LaTeX in the astronomy and cosmology section and it didn't seem to work. I'm just testing a short script here;

[LaTeX Error: Syntax error]

Quote

[ math]\frac{2\times\pi\times8.8\times10^8 m}{8834s}\eq\frac{625900 m}{s}[/math ]

I inserted the spaces after the beginning and before the ending brackets so that the quoted section would appear as the original script I wrote.

Well...obviously I'm doing something wrong. The equation I'm trying to write is:

(2*pi*8.8*10^8 m)/(8834 s)=625900 m/s

Can anyone tell me what I'm doing wrong?

Try this:

[math]\frac{2\times\pi\times8.8\times10^8 m}{8834s} = 625900 m/s[/math]

or this:

[math]\frac{2\times\pi\times8.8\times10^8 m}{8834s} = 625900 m{s}^{-1}[/math]

It seems that what tripped me up is the use of "\eq" for the equals symbol instead of just inserting "=" in the script. Also, it's easier to read the equation if I use "\," before "m" and "s". I remember reading in one of the tutorial pages that spaces between characters are ignored.

Thanks for the help.

You can also use \mbox{} for the m/s. Click on the equation to see the code used to make it:
