1) Read Ch 5.1-5.4 in your classical mechanics text, and review The Mathematics Companion section 2.3 on Vector Analysis for class on Monday 2/13/17

2) Read Chapter 5.5-5.6 in your Classical Mechanics text and review The Mathematics Companion sections 2.4 and 2.5 on partial derivatives and multiple integrats for class on Wednesday 02/15/17

3) Watch our videos on solving the critically damped harmonic oscillator and Springs in parallel and series by Monday 02/13/17, and on the curl of a gradient by Wednesday 02/15/17.

3) Homework #6 is due 2/22/17 4pm in Jiajie Xiao's mailbox in Olin 100. It is:

A) Problems 4.13, 4.14, 5.3, 5.6 and 5.13 from your classical mechanics textbook

- Note that the M matrix in 14a has a typo. Figure out what the typo is.
- You are welcome to solve 14b computationally, but not the rest of the assignment.
- Do 5.6b, and 5.13 using the levi-civita symbol, aka anti-symmetric tensor aka alternating tensor. Any other solutions will be counted wrong.

B) The computational problem assigned in class on 02/17/17.

4) We now have a departmental webpage with links to suggested math videos for review. I encourage you to review the ones on Cross products, Line integrals and Eigenvalues and Eigenvectors.
