Latex Definition and 999 Threads

The support for ##\LaTeX## is great, but there's just one thing I don't like: if I put a newline after the closing \$$ I get too much vertical space after the rendered part. For instance: $$(x_1+\ldots+x_p)^n = \sum_{c_1+\ldots+c_p=n} \frac{n!}{c_1!\cdots c_p!}x_1^{c_1}\cdots x_p^{c_p}$$ As you...

Is it difficult to load additional LaTeX packages? I'm asking because I recently missed St Mary Road: \usepackage{ stmaryrd } I'm not quite sure where it has to happen, server or client side or both, however, my tex editor has it. I'm not so sure whether the browser needs additional modifications.

In this thread https://www.physicsforums.com/threads/circuit-problem-involving-sources-and-resistors.950932/#post-6022243 things looked weird to me and I thought it was the poster's fault but now I see in other threads that there are weird strings of characters which I take to be Latex. I've...

Recently I posted the following text on the Analysis forum ..." ... ... In order to demonstrate that $$K$$ is closed, we prove that $$\mathbb{R}^n\K$$ is open. Indeed, choose $$y \notin K$$ and define $$O_j = \{ x \in \mathbb{R}^n \ \mid \ \mid \mid x - y \mid \mid \gt \frac{1}{j} \}$$ for...
