Math & Science ⇒ Unable to use \subsetneq

[JoseM]

Hello,

I'm using MikTex 2.7 (complete version) with TexnicCenter 1 beta 7.50. I'm unable to use the \subsetneq command - the output dvi file doesn't produce the symbol. Is there any package I need to install or enable? How do I do that? I have the full Miktex (about 1.2 GB!) so I don't think that's the issue.

Thanks,

Jose

Hi Jose,

welcome to the board!
Just load the amssymb package:

Code: Select all

\usepackage{amssymb}

Thanks, Stefan! That was easy.

I have a similar problem with XeLaTeX

Code: Select all

\documentclass[a4paper,oneside,titlepage,12pt]{article}

\usepackage[cm-default]{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\usepackage{amsmath}
\usepackage{amssymb}

\usepackage{xgreek}

\setmainfont[Mapping=tex-text]{DejaVu Sans}

In document section I have some text and some equations (works fine)
when I add the line $A \subsetneq B$ I get an error message (\subseteq produces no error)

Thank you for any ideas

Code: Select all

\documentclass[a4paper,oneside,titlepage,12pt]{article}

\usepackage[cm-default]{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\usepackage{amsmath}
\usepackage{amssymb}

\usepackage{xgreek}

\setmainfont[Mapping=tex-text]{DejaVu Sans}
\begin{document}
$A \subsetneq B$
\end{document}

Is this giving you an error? I don't see one, there is just a warning to inform you, that cm-default is obsolete.
Are your packages up-to-date? Is your distribution up-to-date?

Maybe try to make a minimal working example. This helps to find the real error.

Best regards
Johannes

This is a basic version of text.

Code: Select all

\documentclass[a4paper,oneside,titlepage,12pt]{article}

\usepackage[cm-default,no-math]{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\usepackage{amsmath}
\usepackage{xgreek}

\setmainfont[Mapping=tex-text]{DejaVu Sans}
\parindent=0in

\begin{document}

$A \subseteq B$ \\
\\
$C \subsetneq D$

\end{document}

Here is the error I get in basic version of text.

Code: Select all

! Undefined control sequence.
l.16 $C \subsetneq
D$
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
Underfull \hbox (badness 10000) in paragraph at lines 14--17
[]
[1
] (./basic.aux) )

The first equation is displayed right and the second as CD with no symbol in between.
