How do I properly use LaTeX syntax for multiple lines and spacing in my post?

[zyrolasting]

Hello. I'm new to both PF and LaTeX. I searched the board on this, but could not see a thread that solves my problem.

I have several tex tags to use, but it looks like there can only be so many before the board gives off a database error. After combining the content of tex tags, the text got mushed together.

After some searching, I used both \\ and \\[10] to try and add some new lines and spacing. Neither had any effect on my post previews. (Although they DID work on an online LaTeX editor)

What am I doing wrong?

Many thanks.

EDIT: Found that \newline and \linebreak also do NOT work.

There's a bug that makes the wrong image show up in previews. (There are lots of threads about it). The workaround is to refresh and resend after each preview.

Oh, I actually knew about that from looking through the board, and have successfully updated my previews before. However, newlines are still not included.

Are \newline, \linebreak and \\ supposed to work, or is there something configured so that I need to use something else?

The below code uses all three. At the time of this writing, I am obviously looking at a preview. Even after refreshing, none of them work.

EDIT: Even the forum view doesn't help. Incompatibility with Chrome? Do you guys see the line break?

$$V = n<br /> \\[10]<br /> \newline<br /> \linebreak<br /> V = 23$$

Nope. And this is definitely a server issue, not a browser problem. Since the LaTeX is rendered as an image, it has to appear the same in all browsers.

You can use the multiline AMS environments, like so:

\begin{align*}V&=n \\ V&=23\end{align*}

$$\begin{align*}V&=n \\ V&=23\end{align*}$$
There's also the gather environment, if you don't require specific alignment between the equations, and some others.

Thank you very much, diazona. I appreciate your help!

Here's some more info on muli-line LaTeX. It's the same method that diazona gave, with an explanation of the alignment:
