### Is there life after Calculus?

Screening all 9 hours of LOTR!!!

Yes, there is life after my AP Calculus BC class! This is by far my favorite time of year. This "season," for want of a better term, starts with LIMACON around the ides of March and ICON around the nones of April. Of course, we also start AP Review around this time followed by AP Exam Week during the calens of May! The AP Calculus exams are usually given early during the 2 AP Weeks, so we have a lot of time to kill after Calculus!

As a result, Life After Calculus, aka LAC, has evolved into an art form. Right after the AP Exam, we have a Movie Marathon. Traditionally, our Movie Marathon, starts with "Stand and Deliver," but I couldn't bear to watch that movie this year as Jaime Escalante passed away not so long ago. We usually show one or two other movies to do with math, such as "A Beautiful Mind" or "The Proof." In recent years, we've been doing Science Fiction trilogies like "Star Wars" or "Planet of the Apes," etc. I justify this odd behavior by naming each and every TI Graphing Calculator we've ever used after a scifi character.

TI81 = Obi Wan Kenobi (Star Wars IV)
TI82 = Klaatu (The Day The Earth Stood Still)
TI83 = Ziggie (Quantum Leap TV series)
TI84 = Joshua (Wargames)
TI85 = Johnny5 (Short Circuit)
TI86 = Spock (Star Trek TV series)
TI89 = Hal 9000 (2001: A Space Odysee)
TI92 = Colossus (The Forbin Project)

I use names of characters from these movies and TV series. So, I claim that I'm still looking for a good name for the latest GC, the TI Inspire CAS. For example, last year we saw all 3 versions of "I Am Legend" (Vincent Price, Charleton Heston and Will Smith) and decided to name the Inspire after Dr. Neville! The year before that, I was still looking for a good name for the Inspire, so we viewed "Back to the Future" and chose the name Doc Brown, but it didn't stick. This year, we went crazy and decided to watch all 9 hours of "The Lord of the Rings!" We viewed 2 DVDs worth of LOTR during AP Week and saved the last DVD for these last few days of school. Maybe we'll rename the Inspire as "Nazgul?"

In between these 2 screenings of LOTR, we actually managed to do a lot of math! What follows is a record of some of the topics we covered. We spent some time, LAC Days 1-8, on loose ends in BC Calculus previewing some topics in Calc III and IV. Then I showed my students how to use a bit of SAGE, http://www.sagemath.org
