Below are sample questions representative of the exercises included on this worksheet and related TRIG.106 Communicate solution sets with clear notation skill assessments:

Problem 1Difficulty: Mastery

Solve 2sin(x) = √3 on 0 < x < 4π. Select the correctly written solution set in radians.

A{π/3, 2π/3, 7π/3, 8π/3, 13π/3}

B{π/3, 2π/3}

C{π/3, 2π/3, 4π/3, 5π/3}

D{π/3, 2π/3, 7π/3, 8π/3}

Solution & Explanation:2sinx=√3 gives sinx=√3/2, so x=π/3 or 2π/3 plus 2πk. In (0,4π), k=0 and 1 give π/3, 2π/3, 7π/3, and 8π/3.

Problem 2Difficulty: Mastery

Solve cos²(x) = sin(x) on 0 ≤ x < 2π. Round solutions to the nearest hundredth (radians). Select the correctly written set.

A{0.90, 2.24}

B{0.67}

C{0.67, 2.47}

D{2.47, 3.81}

Solution & Explanation:cos²x = 1−sin²x. Let s=sinx: 1−s² = s → s²+s−1=0. The valid root is s=(−1+√5)/2≈0.618. Then x=arcsin(s)≈0.67 and π−0.67≈2.47.

Problem 3Difficulty: Mastery

Solve cos(2x) = −sin(x) on 0 ≤ x < 2π. Select the correctly written solution set in radians.

A{π/2, 7π/6, 11π/6}

B{7π/6, 11π/6}

C{π/2, 3π/2}

D{π/2, 5π/6, 7π/6}

Solution & Explanation:Use cos2x=1−2sin²x. Then 1−2sin²x = −sinx → 2sin²x−sinx−1=0 → (2sinx+1)(sinx−1)=0. So sinx=1 or sinx=−1/2.
