Recitation of Sep. 19, 2013

We looked at several related rates problems. The method to solve those is always the same:

1. Draw a picture
2. Give name to all quantities. Figure out which are changing and which are constant
3. Figure out what you want to compute, and what you know already.
4. Express what you want in terms of what you know

We worked through Section 3.5.45, 3.9.11, 3.9.23 (C), 3.9.31 (G, still need to finish it).
