Below are sample questions representative of the exercises included on this worksheet and related TRIG.79 Determine missing trig values using identities and quadrant information skill assessments:

Problem 1Difficulty: Mastery

csc(theta) = 3 and sec(theta) > 0. In which quadrant is theta?

AQuadrant II

BQuadrant III

CQuadrant IV

DQuadrant I

Solution & Explanation:csc(theta) = 3 is positive, so sin(theta) is positive (quadrant I or II). sec(theta) > 0 means cos(theta) is positive (quadrant I or IV). The only quadrant with both positive is quadrant I.

Problem 2Difficulty: Mastery

tan(theta) = -8 over 15 and sec(theta) > 0. Find csc(theta).

Solution & Explanation:sec(theta) > 0 means cos(theta) > 0, so theta is in quadrant I or IV. tan(theta) is negative, so theta must be in quadrant IV, making sin(theta) negative. Using the 8-15-17 triangle gives sin(theta) = -8 over 17, so csc(theta) = -17 over 8.

Problem 3Difficulty: Mastery

sin(theta) = -1 over 2 and cos(theta) < 0. What is sec(theta)?

A-2 sqrt(3) over 3

Bsqrt(3)

C2 sqrt(3) over 3

Solution & Explanation:sin(theta) negative and cos(theta) negative places theta in quadrant III. With abs(sin(theta)) = 1 over 2, the reference angle is 30 degrees, so cos(theta) = -sqrt(3) over 2. Then sec(theta) = -2 over sqrt(3) = -2 sqrt(3) over 3.
