PowerPivot - Commonly Used DAX Expressions

Today I will be presenting in a webinar, which by the way is recorded for later viewing, on Commonly used DAX Expressions. You can register (or if you miss it live watch the recording) for this webinar here. I thought it would be great if I could push out the code that I plan to show ahead of time so you could review it immediately following or even during the webinar. Also, if I run out of time you can see what I planned to cover!
