Name: Date: School: Facilitator: 10.04 Graphs of Sine and Cosine Answer these questions: 1. When graphing trig functions in the coordinate plane, what unit of measurement is used on the x-
2. What is a general definition of the amplitude
3. What is a general definition of the period
Complete the following table by determining the amplitude, period, phase shift, and vertical shift for each of the following graphs. Equation Amplitude Period Show your work for the period Vertical Shift 4. 2 2pi/5 2pi/b = 2pi/5 cannot reduce further so the period is 2pi/5 -2 5. 4 2pi 2pi/b = 2pi/1 = 2pi 0 6. 1/2 2pi 2pi/b = 2pi/1 = 2pi 0 7. 5 pi 2pi/b = 2pi/2 = pi 0 8. 3 pi/3 2pi/b = 2pi/6 = pi/3 -1 9. 2 pi 2pi/b = 2pi/2 = pi 3 10. 1/4 2pi 2pi/b = 2pi/1 = 2pi -1 Continue on the next page
