You'll find it in the Dropbox folder<https://www.dropbox.com/sh/fzwt4odnaw3qfvk/ZG9NL-C4K->. You may have questions as to how to do some of the derivations I mentioned or as to clarifications of the short two pages that this is---feel free to ask in class or send an e-mail. See you tomorrow. Bring questions from the recent material. Best, Douglas.
