Math

Math can be typed inline as TeX equations and will show up as MathML in the slides. This is done by using itex2MML.
```
$E=mc^2$
```
appears as $E=mc^2$.
```
$\sum_{n=1}^\infty \frac{(-1)^n}{n} = \ln 2$
```
appears as $\sum_{n=1}^\infty \frac{(-1)^n}{n} = \ln 2$.
```
\[ \sum_{n=1}^\infty \frac{1}{n} \mbox{ is divergent, but } 
 \lim_{n \to \infty} \sum_{i=1}^n \frac{1+ 2 - 2}{i} 
 - \ln n \mbox{ exists.}\]

appears as \[ \sum_{n=1}^\infty \frac{1}{n} \mbox{ is divergent, but } \lim_{n \to \infty} \sum_{i=1}^n \frac{1+ 2 - 2}{i} - \ln n \mbox{ exists.} \]
If the curly bracket below is too small then you probably have not installed all the needed fonts.
