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

AI Thread Summary
The discussion centers on finding a vertical subset symbol in LaTeX, specifically one that points upwards, akin to \subseteq, and a downward variant. The user clarifies that they are looking for symbols to use in a commutative diagram format, rather than standard union and intersection symbols. Suggestions include using the rotating package in LaTeX to achieve the desired orientation of symbols. However, the user encounters issues with the rotating package, as it does not seem to function correctly, printing symbols normally instead of rotated. Other participants suggest converting the DVI file to PS or PDF for proper viewing, as the DVI viewer may not support the rotation feature.

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.
