whoa, I just learned that I can use LaTeX in posts. thank you @ambihelical for the link with all the extra features of qoto.
To test that, here is something I encountered once in a calculus class
\[
\frac{\sin x}{n}=6
\]
@ambihelical hmm. seems very glitchy
@ambihelical too bad. I was excited there for a second. would be good if they fix this.
