A Break…

I hope you’re all enjoying Spring Break. Pre-calc – I talked to an electrical engineer and found out that trig identities are important and actually used quite frequently to simplify signals and systems work. I also learned that many EEs don’t like math and solve most of their problems using computers and simulations…

Are you enjoying Olympic curling? I am.

I find myself too busy to really enjoy the Olympics.  I did get to watch some curling online yesterday.  It is a really interesting game and provides some great physics problems (friction, momentum).  I’m surprised Mr. Groom hasn’t done a Physics of the Olympics lesson yet.

1/26 Recap

Sorry I missed the last couple of days.  I’m really feeling the end of semester crunch.  So tired…

Algebra 2 – Review night tonight 6:30-7:30 (later if absolutely needed) in B-51.  Come ask questions and prepare for the test.  Here is the Review and Key

 

Pre-Calc – We’ve been working on the Chapter 5 Test.  Afterwards we relaxed with some KenKen.

1/21 Recap

Time is Money by practition^r.

Algebra 2 – Talked about the time value of money.  Very interesting and probably the one of the most important topics you’ll learn about this year.  If you missed class today, you’ll need to check out the TVM solver on your TI calculator; I can help you with this, but you’ll need to come see me (or email me).  We started an in-class activity that we’ll finish up tomorrow.  All late work due tomorrow.

 

Pre-Calculus – We had a lot of absences today (swimming, sickness, etc), so the test was postponed until tomorrow.  Remember, all work is due tomorrow.

1/20 Recap

Algebra II – Finished up 6.7 and did lots of examples of solving equations with logs.  HW 46 (6.7) due Monday 1/25.

Pre-Calc – Went over problems on the review. Found a mistake on my review key (theta for problem 2c is 239deg, not 121).  Review Night tonight at 6:30 in my room.  I have to leave at 8:20.

1/19 Recap

Seismograph by mobyd46.

Alg 2 – 6.7 Richter Scale and Newton’s Law of Cooling (we’ll work more on this tomorrow).

Pre-Calc – Reviewed how to use calculator to convert between decimal degrees and deg/min/sec.  Save some time and do these conversions on a calc.  Especially for the review.

Pre-Calculus Chapter 5 Review and Key

Here is the review and key.  I realize there was a lot of converting between degrees and degrees/minutes/seconds.  On Tuesday, I’ll show you how to convert on your calculators.  The test won’t have as much emphasis on this skill.

Chapter 5 Review Key <– error in problem 3c (theta is 239deg,  not 121deg)

Pre-Calculus 5.7 and 5.8 Story Problem Hints/Solutions

As promised – sorry the pics are a little dark.  You’ll need to rotate the pdf when it opens.  I’ll post the Chapter 5 Review Key a little closer to Monday – I want you to take a shot at it on your own first!

Enjoy Winter Ball and the long weekend!

1/15 Recap

Alg2 – We’ll be talking about the Richter Scale next week.  Stay updated on the news coming out of Haiti over the long weekend.

All late work due 1/22

Pre-Calc – All work due 1/22 (Chapter 5B, Chapter 5 Review, and your Legal Description drawing with area).

1/14 Recap

Alg2 – Introduced the natural number and the natural log.

Pre-Cal – Found area of a polygon by breaking it up into triangles.  Law of Cosine is very useful.  Legal Descriptions were handed out to all groups.  We’ll be spending some of tomorrow drawing our plots and calculating acreage.  Chapter 5 test at the end of next week
