9/13 Jenkins

Today the class took the unit circle test and the unit vector test. Both of these tests took a little bit of time but were not that difficult. Also we turned in page 9 of the lab manual before we took the tests. Finally, our homework was to read pages 11 - 12 in the manual. P.S. It is important to study how to convert polar form to unit vector and vice versa. This is what I forgot. That was pretty much all we did during class today. For the question of the day the definition of liquid is a substance that has a surface tension and can be measured in mL and L.
