Below are sample questions representative of the exercises included on this worksheet and related TRIG.3 Construct viable arguments and critique reasoning in trigonometry skill assessments:

Problem 1Difficulty: Mastery
What is the correct solution in that interval? (Enter in radians using pi.)
Solution & Explanation:sin(theta)=cos(theta) implies tan(theta)=1 (where cos not 0), so theta=pi divided by 4 + pi k. Restricting to 0 < theta < pi divided by 2 leaves only theta=pi divided by 4.
Problem 2Difficulty: Mastery
Which critique is correct?
AOn [0,pi], cosine is decreasing, so the implication is reversed: cos(theta) < cos(phi) implies theta > phi
BCosine is increasing on [0,pi]
CThe statement is true as written
DCosine is constant on [0,pi]
Solution & Explanation:Cosine decreases from 1 to -1 on 0..pi. For a decreasing function, smaller output corresponds to larger input, so cos(theta) < cos(phi) implies theta > phi.
Problem 3Difficulty: Mastery
What is the correct number of solutions on pi <= theta <= 2pi? (Enter a number.)
Solution & Explanation:On [pi,2pi], sine is 0 at pi and 2pi and negative in between. It never equals +0.5 on that interval, so there are 0 solutions.
