Teaching Math 4R: Finishing Chapter 12 - Sequences and Series!

Teaching Math 4R: Finishing Chapter 12 - Sequences and Series! 

preCalculus for Seniors finished Chapter 12 this week! We talked about sequences vs. series, finite vs. infinite series, geometric vs. arithmetic, and The Binomial Expansion Series. 

We also tried doing this unit without a Graphing Calculator like the TI-83 we're used to. I showed my students a Computer Algebra System called SAGE. SAGE is based on the python programming language and is very easy to use. SAGE is a free online mathematical programming environment like Mathematica and MATLAB. The ScreenCast below is a playlist including videos from last year using the TI-83 and new videos from this year using SAGE.

Here's our ScreenCasts and SmartNotes for this week:
