Teaching preCalculus: Gimme Sullivan & Sullivan any day!

I just finished a large unit in my preCalculus for Seniors class. We did the chapter on Conic Sections in the Sullivan & Sullivan text pictured above. We had a lot of fun with topics such as Completing the Square, Standard Form, graphing twisted comics using Polar Mode on the Graphing Calculator and Planet Orbits! This unit really lends itself to doing some nice applications such as parabolic mirrors, whisper galleries, ballistics (we also touched on parametric mode) and orbits about the Sun. Can you spell "aphelion?" What follows is a summary of all the ScreenCasts and SmartNotes I recorded for this unit. Enjoy!
