Homework
  • Homework 1: Due September 8, 2017 at the beginning of class. Problem 6 has been postponed, the new homework only has 5 problems.
  • Homework 2: Due October 6, 2017 at the beginning of class. You might find reading Chapter 2 in Acheson useful for solving the last two problems.
  • Homework 3: Due December 15, 2017 at Noon in Aaron's mailbox. In problems 1 and 3, the components of the velocity vector are vx, vy, vz. There was a typo in the original problem 3, there should be no convective derivative on the RHS. The hw has been corrected.
