### Quarter IV, Weeks 2 and 3: ScreenCasts, SmartNotes and Code, oh my!

Last Week, BC Calculus finished a unit on Vector vs. Polar notation. preCalculus was finishing a unit on Limits, Continuity and Differentiability (intro to Calculus). AP Computer Science tied up some loose ends with CH11 "Interfaces and Polymorphism" as CH18 "Recursion." We did CH13 "Inheritance" via GridWorld. I assigned CH19 "Searching and Sorting" as a reading assignment for homework before the AP. I did the same with GridWorld Part IV as we had to start AP Review! Our Youtube Wednesday was again 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 11 minutes per week for 5 weeks! We viewed the 2nd 11 minute installment. NB: That was Week 2 in Quarter IV. Week 3 was devoted to AP Review and other testing, so we don't have anything new.

preCalculus for Seniors
preCalculus was finishing a unit on Limits, Continuity and Differentiability (intro to Calculus). I've been motivating new topics each day with a related Calculus Song from YouTube. There's a lot of great songs on YouTube. Goto YouTube and search for "Calculus Song" or "Calculus Parody" or "Calculus Cover" or "Calculus Carol" or even "Calculus Filk!"

AP Calculus BC
AP Calculus BC finished a unit on Vector vs. 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! We had MCQ IX and CML 4 too.

AP Computer Science
AP Computer Science tied up some loose ends with CH11 "Interfaces and Polymorphism" aka the "implements" key word in java. We also did CH18 "Recursion." We covered CH11 in GridWorld too. We did CH13 "Inheritance" aka the key word "extends" via GridWorld. I assigned CH19 "Searching and Sorting" as a reading assignment for homework before the AP. I did the same with GridWorld Part IV about the Critter class as we had to start AP Review!
Calculus Research LabCRL was back in business as our internet connectivity issues  were finally addressed! So, we finally finished 1.3 Reimann Sums from the Calc2 text implementing Simpson's Rule as a python function. We finished the Derivatives text (calc-1) last semester and started the AntiDerivatives text (calc-2) last quarter. We will also use the Differential Equations text (calc-3) in our final project! These texts are all free for the download as PDFs from http://www.sagemath.org

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