preCalculus, 2015-2016 September: Internet Issues!

preCalculus, 2015-2016 September: 

Internet Issues!
Welcome back! I hope you had a great Summer. Let me just give a quick summary of week 1. I will usually post similar updates once or twice each month.

We started with CH6 SOHCAHTOA this week. Why? Because CC Geometry covered Conics so I'm not doing CH10. Also CC Algebra covers Series so I'm skipping CH12. However CC Algebra does not cover as much Trigonometry as Algebra II & Trig did. So, I'll start with and emphasize Trig this year!

We had a lot of networking and power issues the first week of school, so we didn't get to screencast anything yet. I was going to screencast this class live this year because of all the changes listed above and because we're using the TI-84 Plus C emulator for the first time. We will still use SAGE from time to time, but not as much as in the past. 

Week2 = Finishing Chapter 6!
We focused on SOHCAHTOA. Then we worked on dilation, reflection and translation of the Sine and Cosine functions and their graphs. Finally, we worked on non-linear regression - mostly SinReg. 

Week3 = Chapter 7!

This week we talked about Identity Proofs in Chapter 7. Next week we'll be solving Trig Equations also in Chapter 7.

Week4 = Finishing Chapter 7!

We finished up Chpater 7 by solving trig equations. We also had our SLO_PRE_TEST. Then we had a real PRE_TEST (review in groups) to get ready for our real TEST!

Tom Lehrer's Lobachevsky!
Grace Hopper on 60 Minutes in 1983!
Tom Lehrer's New Math!
(No class Wednesday of Week 4)

Topical Youtubes not for Wednesdays!

NEW preCalculus + TI-84plusC

OLD preCalculus + TI-83

Well, that's all folks!
