10/31 We will create "paper waves" using the definitions of sine and cosine. Examples of those functions are hanging in the classroom now.
11/1 We will graph sine and cosine functions when the angles were measured in degrees and wrote equations of those functions when given the graphs.
11/2 We will repeat everything we do on Thursday, but we used radian measure instead.
***************
11/5 We will develop graphs of secant, cosecant, tangent and cotangent functions and graphed transformations of those functions.
11/7 We will develop graphs of the inverses of the sine, cosine (and tangent) functions. ( I hope we get to the tangent although the concept is the same.) Here is a pdf of that worksheet.
BIG PIECE OF INFORMATION: This year, I will use the following notation to represent functions:
-1 -1 -1
f(x) = Cos (x) f(x) = Sin (x) f(x) = Tan (x)
And this notation will be used to represent inverse graphs that are NOT functions:
y = arccos (x) y = arcsin(x) y = arctan (x)

11/8 We worked application problems! :-) Here is the powerpoint we used.
11/9 I checked to see if students had attempted the applications and the inverse function assignments. Then we reviewed for the quiz on Monday, which will cover the material on all graphs we have covered so far, including reciprocal and inverse functions. Make sure you know about domains and ranges as well. If you're still struggling with the difference between reciprocal and inverse functions, the exercises after this assignment might help. There are answers...
11/6. Students took the trig graphing quiz today . I plan to check The Circle of Life worksheet on Wednesday and the Biorythm lab is due Thursday. On Wednesday, we will do the Slinky lab. I know many students will miss it due to the Renaissance Festival, but I can stay Wednesday and Thursday afternoons so students can make up that lab. It is a good one that shows how amplitudes of trig graphs don't have to be constant.
