Lesson 17 - 6.1 #3 State of Graph of a step function is periodic: Yes (repeats every 2)	Lesson 17 - 6.1 #4 State of Graph of a step function is periodic: Yes (repeats every period)
Lesson 17 - 6.1 #5 State of Graph of a step function is periodic: No (rises and fall with any repeats horizontal)	Lesson 17 - 6.1 #8 State of Graph of a step function is periodic: No (no consistent horizontal repeats)
Lesson 17 - 6.1 #10 State period from table of value: Period, p = 40 (41 - 1 and 81 - 41, goes from 5 to 5)	Lesson 17 - 6.1 #11 State period from graph of cos(x) function: Period, p = 4 (max to max, 4 - 0)
Lesson 17 - 6.1 #17 Study of Ferris wheel movement of dia 20 m. Max. = 24, Min = 4, and period = 2 So D = 14 and A = 10 Formula is	Lesson 17 - 6.1 #21 State period and time of ride or 2.75 cycle given the period in min: Note So 2.75 cycles take 4(2.75) = 11 min.
Lesson 17 - 6.1 #23 Oscillation of spring from ceiling problem: Max. = 14, Min = 6 so D = 10 and A = 4. The period, p = 1 sec So spring oscillates from lowest to highest point in 0.5 seconds.	Lesson 17 - 6.1 #26 Comparing spring oscillation of two springs from a ceiling given their graphs: Graph A: and Graph B: (a) B is closest to ceiling when not in used since D = 10 (b) A makes the largest oscillation since A = 10 (c) A makes the fastest oscillation since 4 oscillations in same period as B.
Lesson 17 - 6.1 #27 Sketch graph of periodic function given: Min = 30 deg C Max. = 110 deg C Lowest point when t = 0 P = 5 hours (time for 1 cycle)
