This is strange. The noparse tag actually works as you can see here:

[tex]f(x)=\begin{cases}1 & x\in\mathbb{Q}\\ 0 & x\notin\mathbb{Q} \\ \end{cases}[/tex]

[tex]x^2[/tex]

For some reason though this code on its own with no dollar signs renders Latex. I have no idea why.

Code:

`\begin{cases}1 & x\in\mathbb{Q}\\ 0 & x\notin\mathbb{Q} \\ \end{cases}`

vBulletin always executes the begin{cases} latex environment directive, regardless what's around it.

You don't even need [tex] markers to make it work.
