Below are sample questions representative of the exercises included on this worksheet and related TRIG.9 Choose a representation that matches the trigonometry situation skill assessments:

Problem 1Difficulty: Mastery
A task asks students to choose a representation for each part: exact values for 11pi/6, a model for tide height over time, and a proof that 1 - sin2 x = cos2 x. Which ordered set of representations is best?
AUnit circle, sinusoidal graph, Pythagorean identity
BRight triangle, bar graph, table of random values
CTangent graph, coordinate scatter plot, unit circle only
DHistogram, unit circle, line graph
Solution & Explanation:The unit circle gives exact values for 11pi/6, a sinusoidal graph models tide height over time, and the Pythagorean identity proves 1 - sin2 x = cos2 x.
Problem 2Difficulty: Mastery
A student wants to compare the rate of change of y=sin x near x=0 with y=cos x near x=0. Which representation is most informative?
AGraphs of both functions near x=0 with tangent-line behavior visible
BUnit circle point at x=pi only
CTable with no x-values near 0
DIdentity sin2 x + cos2 x = 1 alone
Solution & Explanation:Local graph behavior near x=0 shows how quickly each function changes and makes tangent-line steepness visible.
Problem 3Difficulty: Mastery
A graphing tool shows y=sin2 x and y=(1-cos 2x)/2 overlap. Which representation explains the overlap exactly?
APower-reduction identity sin2 x = (1-cos 2x)/2
BUnit circle sign chart only
CRight-triangle diagram for one acute angle
DTable of rounded outputs at two x-values
Solution & Explanation:The power-reduction identity gives sin2 x = (1-cos 2x)/2 for every x, explaining the overlapping graphs exactly.
