Re: math symbol for "is an element of"

[<type@projectivespace.com>]

My sincere apologies. I tried to do my homework to avoid wasting everybody else's time with a silly question, but apparently I did not do so adequately. You're quite right -- it works with no problem. It was something else nearby that was causing my minimal example (apparently not minimal enough) to fail.

That being said, the link to "\in" on the Math Basics page does point to the wrong place (the "\in" command used for references). I'll go correct that as my penance for asking such a ridiculous question.

Thanks, and again my apologies,


Sciurus

Do you have a example where \in fails?

\starttext

\m {A \in B}

\startformula
A \in B
\stopformula

\stoptext
