Can I put Math or Equations in my Posts?

Yes! WordPress.com supports $\LaTeX$ , a typesetting system that’s really good at formatting mathematical formulas.

To include $\LaTeX$ code in your post, use the following.

$latex your-latex-code-here$

So, for example,

$latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$

produces

$i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$

If your $\LaTeX$ code is broken, instead of the equation you’ll see an ugly yellow and red error message. Sorry, we can’t provide support for $\LaTeX$ syntax, but there are plenty of useful guides elsewhere online. Or a quick post in our forums might find you a solution.

Can I change the size of the LaTeX?

Yes by specifying an s parameter after the $\LaTeX$ code.

$latex \LaTeX&s=X$

where X goes from -4 to 4 (0 is the default). These sizes correspond to $\LaTeX$ ’s font size commands:

`s=`	font size	Example
-4	`\tiny`	$\LaTeX$
-3	`\scriptsize`	$\LaTeX$
-2	`\footnotesize`	$\LaTeX$
-1	`\small`	$\LaTeX$
0	`\normalsize (12pt)`	$\LaTeX$
1	`\large`	$\LaTeX$
2	`\Large`	$\LaTeX$
3	`\LARGE`	$\LaTeX$
4	`\huge`	$\LaTeX$

Can I change the color of the rendered image?

WordPress tries to guess the background and foreground colors of your site and generates the $\LaTeX$ image accordingly. But, yes, you can change the colors.

You can specify bg and fg parameters after the $\LaTeX$ code to change the background and foreground colors, respectively. The colors must be in hexadecimal RGB format: ffffff for white, 0000ff for bright blue, etc.

$latex \LaTeX&bg=ffcccc&fg=cc00ff&s=4$
