1. 2.6 Graphing Sine and Cosine Functions Warm-up (IN) 1.Identify the transformations from to Learning Objective: To graph sine and cosine functions and to determine the amplitude and period of sinusoidal functions.

2. NOTES "Sinusoidal FUNctions" x=angle in radians F(x)=value of function Sin and Cos functions have a period of So we will graph the interval

3. Cycle - 1 period, or…the time it takes to repeat Transformations! amplitude horiz. stretch/ compression horiz. shift vert. shift

4. Ex 1 - Shifts right units

5. Ex 2 - Shifts up 2 flips

7. Ex 3 - Amp is 2

8. Ex 4 - Horiz compression by 3 Find the period! Divide by 4 to get units

9. HW – pg. 186 #9-18,21-23,26-30,35 Out – Describe the transformations of the sine curve. Summary – I have a question about…or… Wow! I… Don’t forget about POW!!
