HW: Complete book 13.4 & 13.5 tonight if you have not yet done so. These will be collected tomorrow, 5/13.
We did a review of identifying the amplitude and period of a given sine or cosine function. Then students completed their quiz 13.2 - 13.3.

We reviewed vocabulary related to the graphs of sine & cosine: period, periodic function, cycle, frequency, amplitude, midline, max/min values. We examined the effects of a, b, & c for the graph y = a sin(bx + c).
We also highlighted the formula that the period = 2 pi/b . HW: Book 13.5 page 865- 867 16 - 20, 22, 24, 28 - 32, 35, 38, 42, 46 - 50 Quiz 13.2 - 13.3 is tomorrow. We completed the the TI-Nspire activity on the graphs of sine and cosine functions. Students are to complete the following book problems. You may need to refer to pages 852 - 855 for additional examples/vocabulary.
HW: Page 856 - 858 12 - 14, 27 - 30, 37, 38, 40, 55 - 64, 66 - 69 We went over WS 13-3 1 - 28. Students are to work on the back of the first page (the step by step word problem). Students then completed the conversion of given degree measurements into radians. Students used the TI-Nspire calculators to investigate the graphs of trig functions. Students collected data on the x-values of the unit circle (cosine function) and also on the y-values of the unit circle (sine function). We will complete the graphs tomorrow in class.
HW: Complete your tenmarks assignment (s) and the back of the first page of the 13-3 packet. We talked about the unit circle (circle at the origin with a radius of 1) and found that we could describe an angle using the arc length of the unit circle (called a radian) instead of using degrees. We converted between radian measure and degree measurements.
We also used the formula s = r*theta (radian measure only) to get the arc length of any sized circle.

WS 13.2 was collected and students received a second WS 13.2 that some completed in class.
HW: WS 13.2 1 - 11 all and complete 2 columns (left and right) from 12 - 41. Complete the 3 problems on the back. Students had 15 minutes to complete their chapter 8 test. Then we discussed how to graph and angle in the coordinate plane. All angles start on the positive x-axis and the positive direction is to move to the left (counterclockwise). We completed the vocabulary match as well as finding angles that are coterminal.
