#### Using LaTeX

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

**$****latex your-latex-code-here$**

For example,

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

produces

If you wish to copy and paste this formula to test it out, we recommend pasting it as plain text.

In the WordPress Editor, you can add LaTex formulas in plain text by pasting it into a Custom HTML block, which looks like this:

To preview the equation, Click on the Preview button in the top right-hand side of the editor and the equation will show on the live site.

#### LaTeX Error

If your code is broken, instead of the equation you’ll see a yellow and red error message, shown below.

We can’t provide support for syntax, but there are plenty of useful guides 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

#### More Information

For code, you can use an online generator like HostMath.
