in the quick reply box there's a tex sandbox

[eqn]m \frac{dV^\mu}{d\tau}=\frac{e}{c}F^{\mu}_{\nu}V^{\mu}[/eqn]

Fact:
[eqn]\pi = \lim_{n\to \infty}\frac{e^{2n}n!^2}{2n^{2n+1}}[/eqn]

I used to advise people to always use \displaystyle in order to automatically have big, pretty operators like sigmas, integral signs and such, but this isn't absolutely necessary.

It depends on which tags you use. One or the other of the math or eqn tags kicks it up automatically, without invoking the above command.

You can also right click on any TeX in /sci/ to get a dialogue revealing (almost, usually) exactly what the code was/is.

Furthermore, if you fuck up a post, you can wait a few minutes, delete your post, then try again. Just don't fuck up too many times, as 4chan limits how many posts you can delete in a given short time interval.

eqn tags are for newline equations
math tags are inline equations

Let [math] \exp: \mathbb{R} \to \mathbb{R}
[/math] be the unique solution [math] y = \exp(x) [/math] to the first order ODE
[eqn] \frac{\mathrm{d} y }{\mathrm{d} x } = y [/eqn]
satisifying the initial condition [math] \exp(0) = 1 [/math].

How tf did I never realize this, I thought that was there to tell you the box had formatting.

LaTeX threads are as old as /sci/ itself, anon. It is far from a new idea.

People stopped making them after /prog/ (textboard) was deleted and we started getting all those UTF-8 cancerposters spamming /sci/.

Limits look better if you do it like this:
\pi = \lim\limits_{n\to \infty}\frac{e^{2n}n!^2}{2n^{2n+1}}

Use \limits to get better looking integral/summation rendering too.

why does latex require so many keystrokes

That is actually not reliable.

If you write certain commands leaving little white spaces between them, they will render in the TEX test thing. But then when you post they will not render.
