Adding LATEX to posts

WordPress supports LaTeX, a typesetting system that’s really good at formatting mathematical formulas and equations.

Using LaTeX

To include LaTeX code in your post, use the following:

$latex your-latex-code-here$

So, for example,

$latex ihbarfrac{partial}{partial t}left|Psi(t)right>=Hleft|Psi(t)right>$

produces

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

LaTeX Error

If your LaTeX code is broken, instead of the equation you’ll see an ugly yellow and red error message. One thing to keep in mind is that WordPress puts all of your LaTeX code inside a LaTeX math environment. If you try to use LaTeX that doesn’t work inside the math environment (such as begin{align} ... end{align}), you will get an error:

LaTeX&s=X

LaTeX Size

You can change the size of the LaTeX 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 $latex LaTeX&s=-4$
-3 scriptsize $latex LaTeX&s=-3$
-2 footnotesize $latex LaTeX&s=-2$
-1 small $latex LaTeX&s=-1$
0 normalsize (12pt) $latex LaTeX&s=0$
1 large $latex LaTeX&s=1$
2 Large $latex LaTeX&s=2$
3 LARGE $latex LaTeX&s=3$
4 huge $latex LaTeX&s=4$

LaTeX Colors

WordPress tries to guess the background and foreground colors of your site and generates theLaTeX image accordingly. But, 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.

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

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

LaTeX Packages

WordPress uses standard LaTeX with the following packages:

  • amsmath
  • amsfonts
  • amssymb
