Does anyone know the symbol for a vertical subset symbol Latex help

[Tzar]

Does anyone know the symbol for a vertical subset symbol?? i.e the equivalent of \subseteq
but which points up (i also need one which points down)?? Thank for the help

You mean union and intersection? \cup and \cap

no no. what I am trying to achieve is like a commutative diagram but with with "subset" symbols instead of arrros. So for example, one of the ros may be A\subseteq B. I need the analogue of this but for columns. The \cup and \cap sublos won't do, for they don't have a slash next to them, indicating the possibility of equality...

Maybe you should use the rotating package for LaTeX.

How do I do that?? Is there a specific functon that allow me to rotate any given symbol??

Thank you ver much for your help..However, for some reason when I try to use the rotating package, it simply doesn't work. I type the command to rotate (after loading the package) and it simply doesn't rotate, it just prints the symbol (or any other text when I try) normally. I don't get an error message either. If comment out the line \usepackage{rotating} then I do get an error which I guess means it recognise the command \begin{rotating}...

has any ever had a similar problem?

It might be that the dvi viewer doesn't recognize what is happening.
Try to convert the dvi to ps or pdf, then view accordingly.
