When you are blogging about mathematics, you can make your mathematical expressions look professional using . Here are some things you should know.

  1. There are plugins available, but if you are hosted on wordpress.com, then you can stick with using the built-in capability.
  2. If you are not using the plugins, your expressions should begin with $latex, and end with $. For example, latexInWordpressExample will generate this: .
  3. If you are not happy with the size of the output, you can add a size parameter. Instead of ending with a $, end your expression with &s=4$, for example. See the wordpress.com help page for details.
  4. You can copy expressions and equations from desmos.com, and paste them into your blog post, already marked up with . This is a good way to learn about .
  5. If you are going to do a lot of , it is worth installing MacTeX so that you can use LaTeXit to build your mathematical expressions.

Here are some examples:

How it looks when typeset
e=mc^2
\frac{d}{dx} \ln x = 1 / x
f'(x)=\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}
\displaystyle f'(x)=\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}
e^{\pi i} + 1 = 0
\sqrt{a^2 + 2ab+ b^2} = |a+b|
\displaystyle \sum_{n=1}^\infty \frac{1}{n^2} = \frac{\pi^2}{6}
\displaystyle 1 - \frac{1}{2} + \frac{1}{3} - \frac{1}{4} + ... = \ln 2
