First Full Week of Quarter Three "3 Key Things"

As we approach February and launch the Third Quarter - Here are 3 sets of 3 things to consider

 3 Key  “Graded” Activities

·         HW 4.3b (Due next Class) - 206/11,13,17,22,24,27,29,39-45 AND Ch 4 Practice Test

        Practice Test Answer Key will be posted at  http://www.mpsri.net/page.cfm?p=1567 

·         Chapter 4 Test on Thursday (Day 3)

·         Alternative Assessment (Starting this Week Due Next Tuesday)– Cool Trig. Graphing Mini-Project (Preview of the Project Expectations are posted at my Middletown Webpage (see link above). 

3 Key Resources

·         Graphs of Trigonometric Functions Reference Sheet  (use it while doing CW/HW)

·       ~Trig. Graphing Procedure Sine/Cosine Functions~

·         A new Google document assignment sheet will be added and linked to this page (but is not yet.  Our current assignment sheet can be found at ….(stay tuned) This Live Document can be accessed any time to see what you  should be working on.

3 Key Takeaways from Today’s class (Monday, January 30, 2012 – Day 3)

·         Our graphs have to show 6 ” key features” and  there should be a table of values showing our exact abscissa values (pi/4, pi/2, etc.) and important ordinates (fancy or mathematically precise words for (x,y) coordinates. 

·         We can use the graphing calculator to “check” the accuracy of our key features but must know how to adjust the window, table, tableset, etc.  This systematic approach to graphing Trig. functions will take practice but will pay off in the long run

·         There are two Algebraic forms of Trigonometric equations y = asinb(x-c) + d (when the b is “factored out”) and y = a sin(bx + c) which matches standard formats on our new reference sheet.  The “factored out” form  is better for identifying phase shifts and relating to earlier non-Trigonometry functions, shifts, etc.
