Last Week, BC Calculus started a unit on Vector vs. Polar notation. preCalculus started a unit on Limits and Continuity (intro to Calculus). AP Computer Science was finishing up GridWorld Part 3 with the Jumper class. Our Youtube Wednesday was about Steve Jobs, "One Last Thing." This PBS special will take the next several weeks of YouTube Wednesdays and TED Tuesdays as we are only viewing about 10 minutes per week!

__preCalculus for Seniors__preCalculus for Seniors started a unit introducing the concepts of Calculus. We did a lot with limits and continuity. We also defined the Derivative and even talked about the Power Rule!

__AP Calculus BC__**AP Calculus BC started Chapter 12 talking about Vector and Polar notation. We stressed the similarity of Polar and Parametric modes. So, once we figured out how to calculate slopes and arc lengths parametrically, we tried to do the same with polar graphs. We also talked about polar area! Next week is AP Review already!**

__AP Computer Science__APCS was finishing GridWorld part 3 writing the JumperRunner and Jumper classes! After Jumper we will do Recursion and AP Review! It is getting down to crunch time. We need to finish up this week and then do a bit of AP Review next week. The Exams are the following week???

**CRL was down all last week as we did not have internet access! We finished the Derivatives text (calc-1)and started the AntiDerivatives text (calc-2). We will also use the Differential Equations text (calc-3). These texts are all free PDFs from http://www.sagemath.org**

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

Learning with Technology,
