Introducing the nsubseteq Tex Command

The \nsubseteq Tex command is used to signify "not a subset of". It is similar to the \subseteq command, which is used to signify a set being a subset of another set.

How to use it

To use the \nsubseteq command, simply include it in your TeX code, like this:

$A\nsubseteq B$

This will output "A is not a subset of B".

More Examples

Here are some more examples of using the \nsubseteq command:

$X\nsubseteq Y$

Output: "X is not a subset of Y"

$1,2,3\nsubseteq \{1,2,3,4,5\}$

Output: "1,2,3 is not a subset of {1,2,3,4,5}"

$S\nsubseteq T$

Output: "S is not a subset of T"

Conclusion

The \nsubseteq command is a useful tool in TeX for specifying when a set is not a subset of another set. It can be easily inserted into your code and can help make your mathematical expressions more clear and concise.
