Below are sample questions representative of the exercises included on this worksheet and related TRIG.10 Check solutions using multiple methods skill assessments:

Problem 1Difficulty: Mastery

Two methods solve 2sin(x) = √2 on 0 ≤ x < 2π. Method 1 simplifies to sin(x)=√2 over 2 and lists x = π over 4 and 3π over 4. Method 2 uses arcsin(√2 over 2) and lists only x = π over 4. Which conclusion is correct? Answer with A, B, C, or D.

AMethod 2 is correct; there is only one solution

BMethod 1 is wrong because arcsin is exact

CBoth methods give the same complete set

DMethod 1 is correct; Method 2 missed a second solution

Solution & Explanation:sin(x)=√2 over 2 occurs at π over 4 and 3π over 4 in [0,2π). arcsin gives the principal value π over 4, so it must be extended to capture the second solution. Thus Method 1 is correct.

Problem 2Difficulty: Mastery

A student claims cos(x) = sin(π over 2 − x) for every real x. Which verification is best? Answer with A, B, C, or D.

ATest only x = 0, then conclude it’s always true

BUse arccos on both sides and set inputs equal

CGraph y = cos(x) only

DUse the cofunction identity sin(π over 2 − x) = cos(x)

Solution & Explanation:The cofunction identity directly shows sin(π over 2 − x)=cos(x) for all x, so it verifies the statement without relying on a single test point.

Problem 3Difficulty: Mastery

Principal−value evaluation: Compute arctan(tan(−3π over 4)). Answer with A, B, C, or D.

A−3π over 4

B3π over 4

Cπ over 4

D−π over 4

Solution & Explanation:tan(−3π over 4)=1. arctan(1)=π over 4, which lies in the principal range (−π over 2, π over 2).
