Below are sample questions representative of the exercises included on this worksheet and related TRIG.56 Model periodic phenomena with trigonometric functions skill assessments:

Problem 1Difficulty: Mastery

The model y = 18 + 4sin((2pi/7)(x - 2)) fits a 28-day data set. Which concise interpretation is correct?

AAmplitude 4, midline 18, period 7 days, shifted right 2 days, domain 0 <= x <= 28 for the data set

BAmplitude 18, midline 4, period 2 days, shifted left 7 days, domain all real numbers

CAmplitude 4, midline 18, period 14 days, shifted right 7 days, domain 0 <= y <= 28

DAmplitude 7, midline 18, period 4 days, shifted right 2 days, domain 2 <= x <= 7

Solution & Explanation:The coefficient 2pi/7 gives period 7, the amplitude is 4, the midline is 18, and x - 2 shifts the graph right 2. The data window gives the domain.

Problem 2Difficulty: Mastery

A migration count averages 1200 animals, ranges from 400 to 2000, has a period of 365 days, peaks near day 90, and is used for one year. Which model and domain fit?

AM(d) = 1200 + 800cos((2pi/365)(d - 90)), 1 <= d <= 365

BM(d) = 1200 - 800cos((2pi/365)(d - 90)), all real d

CM(d) = 400 + 800sin((2pi/90)d), 1 <= d <= 365

DM(d) = 1200 + 1600cos((2pi/365)(d - 90)), 90 <= d <= 365

Solution & Explanation:The amplitude is (2000 - 400)/2 = 800 and the midline is 1200. A peak at day 90 fits positive cosine, and one year uses 1 <= d <= 365.

Problem 3Difficulty: Mastery

If a data set is periodic with period 10 and starts at its minimum, then y = D + A cos((2pi/10)t) with A positive will start at the minimum.

ATrue

BFalse

Solution & Explanation:A positive cosine model starts at a maximum when t = 0. To start at a minimum, use negative cosine or a horizontal shift.
