WordPress allows you to use a lot of latex typesetting capabilities in this blog. To enter into “math mode,” when typing a post or a comment, use the command ‘dollar sign’latex. After typing this, you can use a large portion of the latex library of mathematical typesetting commands. When you are done writing mathematics, close math mode with another ‘dollar sign.’ WordPress does not support a ‘display environment’ (achieved in your favorite latex editor with either ‘double dollar sign’ or ‘\[ … \]’), but you CAN control the size of the typeset mathematics (before closing math mode, enter ‘&s=’ followed by a number between -4 and 4; here the number 0 is the ‘standard font size’ so that negative numbers will shrink the output while positive numbers increase the size of the output.

Examples:

Here is an inline equation , which is fairly robust (even allowing fractions in the bounds of integration). [code: ‘dollar sign’latex \int_{0}^{\frac{\pi}{2}} \tan(x) dx &s=2’dollarsign’]

The next two equations are “center justified” in the wordpress text editor, to act as display equations.

[code: ‘dollar sign’latex \begin{bmatrix} 45 & 32 & 12\\ 13 & \frac{1}{x} & \infty \end{bmatrix} &s=3’dollar sign’]

[code: ‘dollar sign’latex \begin{cases} f(x) & x= 45\\ g(x) & x = 32 \end{cases} &s=-2’dollar sign’]
