### Quarter II, Week 7: ScreenCasts, SmartNotes and Code, oh my!

AP Calculus BC finished Unit 6 and had a test on metrics aka measurement theory (applications of the definite integral). Last week we reviewed area and talked about volumes of revolution (disk, washer, shell) in dx and dy. This week we finished volumes with known cross sections as well as arc length and surface area.

AP Computer Science just finished the lab at the end of Grid World Part II (CircleBug, SpiralBug and ZBug). Sorry, I don't post labs online! After break we are going to do loops and arrays.

Calculus Research Lab finished CH4 with exercises on the derivatives of trig and inverse trig functions.

This was the week before the holiday break. So, we were done with all the above by Thursday. Friday was BZFlag day in my computing class and my math classes went preCalculus or Calculus Caroling all over school!

HTH and I hope you enjoyed this week's notes!
