Below are sample questions representative of the exercises included on this worksheet and related TRIG.61 Interpret real world meaning of sinusoidal parameters skill assessments:

Problem 1Difficulty: Mastery

A lab writes a sine model where time is scaled inside the parentheses. Model: y(t) = 3 + 2*sin((2pi divided by 12)*(4*(t - 1))), where t is in seconds. Which interpretation is correct?

AThe period is 12 seconds because of the 12 in the formula.

BThe graph is shifted right by 4 seconds.

CThe period is 3 seconds because scaling by 4 makes the cycle 4 times faster.

DThe amplitude is 12.

Solution & Explanation:The base period would be 12, but multiplying (t-1) by 4 compresses the graph horizontally by 4, so the new period is 12/4 = 3 seconds.

Problem 2Difficulty: Mastery

A student models the height of a bouncing ball with a sinusoid for a short interval. Model: h(t) = 0.9 + 0.3*cos((2pi divided by 0.6)*(t + 0.05)), where t is in seconds. Which statement correctly interprets (t + 0.05)?

AThe graph is shifted 0.05 seconds to the left (the bounce cycle happens earlier).

BThe period is 0.05 seconds.

CThe amplitude is 0.05 meters.

DThe average height is 0.05 meters.

Solution & Explanation:t+0.05 equals t-(-0.05), so the phase shift is -0.05 seconds: a left shift of 0.05 seconds.

Problem 3Difficulty: Mastery

A factory models the temperature in an industrial oven during a repeating control cycle. Model: T(t) = 450 + 30*sin((2pi divided by 5)*t), where t is in minutes. Which interpretation of the 30 is correct?

AThe temperature repeats every 30 minutes.

BThe temperature can be 30 degrees above or below the average of 450.

CThe average temperature is 30 degrees.

DThe temperature starts 30 minutes late.

Solution & Explanation:The coefficient 30 is the amplitude, so it gives the maximum deviation from the midline 450.
