Review Sec 13-1 to 13-4

Bellwork reviewed finding the period, amplitude, and equation of the midline for periodic functions.

The remainder of the period we continued our discussion on Sec 13-4, The Sine Function.  Students learned to graph one period of a Sine equation and also write the equation from a given graph.

Hwk #27 is due Friday.  Sec 13-4

Pages 738-739

Problems 13, 14, 22, 23, 27, 29-32, 42

Bellwork reviewed using the Unit Circle to find exact values of Sin, Cos, and Tan.

Hwk #26 is due today.

The remainder of the period we began our discussion on Sec 13-4, The Sine Function.  Students used the graphing calculator to explore how the values of a and b in the equation y=aSinbx affect the graph of y=Sinx.

Unit Circle Quiz will be either Thursday or Friday of this week.

1st Hour:  For bellwork students practiced filling out the degrees and radians on the Unit Circle.

3rd Hour:  Bellwork reviewed problems from Sec 13-2

Hwk #25 is due today.

1st Hour:  The remainder of the period we discussed how to fill out the coordinates on the Unit Circle then using it to find exact values for the Sin, Cos, and Tan of angles on the Unit Circle.

3rd Hour:  The remainder of the period we discussed how to fill out the angles in both degrees and radians on the Unit Circle.  We reviewed the properties of Special Right Triangles because this skill will be used when filling out the coordinates on the Unit Circle.
