When adding articles, comments, etc. to the site, your text input will be processed by an extended version of markdown to produce pleasing (as least we think so) visual output that includes links, basic formatting, and images. Markdown is designed to be very easy to read in plain-text and it's syntax is very well documented on the web. If you don't have much experience writing in Markdown, this site allows you to play around. Further information about Markdown syntax can be found here. We've also extended Markdown in two ways that are specific to this site. Please see below for details. Inline math

We've extended markdown with MathJax to allow support for inline math. As things can get complicated when you mix the two, we recommend the following when you need to write math:

To have inline tex, do:

$\sum_{n=1}^\infty {1\over n^2} = {\pi^2\over 6}$

which will display like: ∑∞n=11n2=π26

. For paragraph math, do:

$$\sum_{n=1}^\infty {1\over n^2} = {\pi^2\over 6}$$


Which will look like:

$\sum_{n=1}^\infty {1\over n^2} = {\pi^2\over 6}$

To do a literal $, do \$

### Internal site links

To generate a link to lecture 1, use:

[lecture 1](classlecture:intro)

If you want to know the short name of a lecture (e.g., intro above), just go visit the lecture on the site. You'll be able to read the short name of a lecture right out of it's url. For example, lecture 1's url is lecture/intro.

To generate a link to lecture 1, slide 1, use:

[lecture 1, slide 1](classlecture:intro[slide_001])

As with links to lectures, if you want to know the name of a slide, just take a look at the slide's url. All lecture slide urls on the site are of the form lecture/lecturename/slidename.

Currently, articles don't have short names, only numerical ids. To generate a link to article 1, use:

[article 1](classarticle:1)
