Sorry for the wrong explanation. I meant that generally is safer to use {} (typical case is ^ or \sqrt).

\[a^23\neq a^{23}\]

I consider the extraspace the better one too, that's why I suppose {} gets the right behavior, even in common math functions.
Anyway, if you don't like extraspace use a ...

The right use of a math function is by enclosing the arguments within {}. The following two log functions are equally spaced.

$\log{\left(3\right)}+\log{(3)}$

By writing this

$\log(3)$

you are not feeding the function with its argument...
Perhaps the following shows the difference between ...

May be you are searching for the amsmath package ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf

In general consider that the basic latex commands are enough powerful to create any kind of block you require. Basically, you could write your book just by means of \newtheorem and ...

Consider to have look to symbols-a4.

I'm not sure to understand what you mean with ...
> Can you adjust the height of the centre of the delimiters with respect to the contained maths?

Maybe you want just play with a raisebox.

Hello,
this is probably due to a limit (or a bug) of multirow package. The multicolumn head
is too long and sub-columns fail in being distrubted evenly.
You can use hspace. The following is not a definitive solution, but works.

\begin{tabular}{c|c|c|c}

Hello,
I found the answer by myself in the 5002.EPSF_Spec.pdf of adobe .

Now I'm able to write in Tex, get the eps, include it in my ps and translate it where I need.

Hello,
I need a way to specify the placement of a math text inside a postscript source according to default postscript coordinates (lower-left edged) (don't ask me why?:).
At the beginning my reasoning was the following:


1) Write my text as mymath.tex
2) Get a mymath.dvi using latex
3) Get a ...

The code above removes the footer completely. If you want both footer and header and no page numbering, you can conveniently use the fancy package as follows:
