Day 18: Linear Algebra

Today:

• return 2.2 homework (#14 and 22) -- sorry, delayed!

• Homework 2.3 due next time.

• There's a talk right after class, if anyone's available: my dissertation advisor is speaking on "Geostatistics". There are plenty of applications of linear algebra therein -- but more importantly, there will be cookies....

• For Wednesday: David will lead us into chapter 4 (section 4.1) (we'll delay finishing section 3.1)

• Questions/Comments on old stuff?
