Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.97 Simplify Expressions Using Trigonometric Identities skill assessments:

Problem 1Difficulty: Mastery
Simplify: (sec(x) + csc(x)) / (sec(x)·csc(x))
A1
Bsin(x) − cos(x)
Csec(x) + csc(x)
Dsin(x) + cos(x)
Solution & Explanation:sec·csc = (1/cos)(1/sin)=1/(sin cos). Multiply: (1/cos + 1/sin) ÷ (1/(sin cos)) = (1/cos + 1/sin)(sin cos)=sin + cos.
Problem 2Difficulty: Mastery
Simplify: (sin(3x) − sin(x)) / cos(2x)
Asin(2x)
B2sin(2x)
C2sin(x)
D2cos(x)
Solution & Explanation:Use sinA−sinB=2cos((A+B)/2)sin((A−B)/2). sin3x−sinx=2cos(2x)sin(x). Divide by cos(2x) to get 2sin(x).
Problem 3Difficulty: Mastery
Simplify: (cos(3x) + cos(x)) / cos(2x)
A2sin(x)
B2cos(x)
Ccos(x)
D2cos(2x)
Solution & Explanation:Use cosA+cosB=2cos((A+B)/2)cos((A−B)/2). cos3x+cosx=2cos(2x)cos(x). Divide by cos(2x) to get 2cos(x).
