Below are sample questions representative of the exercises included on this worksheet and related TRIG.5 Use appropriate tools strategically in trigonometry skill assessments:

Problem 1Difficulty: Mastery

A temperature model is T(t) = 3 cos((2pi divided by 5)t) + 1, where t is in hours. You need to graph 0 <= t <= 20 and count the cycles. Which setup is best?

ADegree mode; x-window 0 to 20; y-window -1 to 1.

BRadian mode; x-window 0 to 360.

CPolar mode with r = 3 cos((2pi divided by 5)t) + 1.

DRadian mode; x-window 0 to 20; y-window about -3 to 5; graph the function and use TRACE if needed.

Solution & Explanation:The expression contains pi, indicating radian measure in the trig input. An x-window of 0 to 20 matches the time interval, and a y-window that includes the range (1 +/- 3) helps you count cycles clearly.

Problem 2Difficulty: Mastery

For y = -2.1 sin(0.45x + 2.7) + 9.8, the calculator's Maximum feature (searching x >= 0) reports a peak at x = 4.47 with y = 11.90. What is the x-value of the first maximum, to the nearest hundredth?

Solution & Explanation:The Maximum feature outputs the x-coordinate of the peak. It reports x=4.47 for the first maximum when searching x>=0, so the answer is 4.47.

Problem 3Difficulty: Mastery

A model is y = -2.1 sin(0.45x + 2.7) + 9.8 (radians). You need the first maximum value for x >= 0, and solving it algebraically is messy. Which calculator tool is most direct?

AUse Zero; maxima occur where y = 0.

BUse LinReg to 'smooth' the maximum.

CGraph the function and use the Maximum feature with a left bound at x = 0.

DSwitch to Degree mode so the phase shift disappears.

Solution & Explanation:A maximum is a peak on the graph. Using the Maximum feature after restricting the search to x>=0 directly returns the first peak without heavy algebra.
