LaTeX
WordPress.com supports , a typesetting system that’s really good at formatting mathematical formulas and equations.
Using LaTeX
To include code in your post, use the following:
$latex yourlatexcodehere$
So, for example,
$latex i\hbar\frac{\partial}{\partial t}\left\Psi(t)\right>=H\left\Psi(t)\right>$
produces
Note: If you wish to copy and paste this formula to test it out, we recommend pasting it as plain text.
LaTeX Error
If your code is broken, instead of the equation you’ll see an ugly yellow and red error message. Sorry, we can’t provide support for syntax, but there are plenty of useful guides elsewhere online. A quick post in our forums, or the Stack Exchange LaTex forum, might find you a solution. One thing to keep in mind is that WordPress puts all of your code inside a math
environment. If you try to use that doesn’t work inside the math
environment (such as \begin{align} ... \end{align}
), you will get an error:
LaTeX Size
You can change the size of the LaTeX by specifying an s
parameter after the code.
$latex \LaTeX&s=X$
Where X goes from 4 to 4 (0 is the default). These sizes correspond to ‘s font size commands:
s= 
font size  Example 

4  \tiny 

3  \scriptsize 

2  \footnotesize 

1  \small 

0  \normalsize (12pt) 

1  \large 

2  \Large 

3  \LARGE 

4  \huge 
LaTeX Colors
WordPress tries to guess the background and foreground colors of your site and generates the image accordingly. But, you can change the colors. You can specify bg
and fg
parameters after the 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.
$latex \LaTeX&bg=ffcccc&fg=cc00ff&s=4$
LaTeX Packages
WordPress.com uses standard with the following packages:
 amsmath
 amsfonts
 amssymb
