Re: [Maxima-discuss] Correct Syntax for Greek Letters in Maxima Batch Files for LaTeX Export

[Foad S. F. <f.s...@gm...>]

Following up on my earlier query about using Greek letters and generating
LaTeX output from Maxima batch files, I have encountered a specific issue
with superscript notation. According to the documentation and examples
(such as those found on this page
<http://www.hippasus.com/resources/symmath/maximatypeset.html>, I
understand that Maxima can directly convert expressions to LaTeX format.
For example, running:

```maxima
tex(sigma_2(x,y) = sin(alpha^2 + beta^2));
```
correctly yields:

```latex
$$\sigma_{2}\left(x , y\right)=\sin \left(\beta^2+\alpha^2\right)$$
```
However, when I try to use characters in the superscripts, as in:

```maxima
tex(sigma_x(x,y) = sin(x^2 + y^2));
```
Maxima seems to misinterpret the subscript and outputs:

```latex
$${\it sigma\_x}\left(x , y\right)=\sin \left(y^2+x^2\right)$$
```
which is not what I expected. The subscript `x` is incorrectly typeset as
part of the function name rather than as a subscript.

Could anyone clarify how to properly format expressions with subscripts and
superscripts in .mac/.mc files so that they are correctly rendered in
LaTeX? Any pointers on ensuring accurate typesetting would be greatly
appreciated.

Thank you for your help.
