Sample Question 1
Graph one complete cycle of 4(cos 2x - ? /2).

4(cos 2x)

4(sin 2x)

4(cos2x−1/2)

4(cos x - 1/2)

Sample Question 2
Find the equation to match:

Y = 5cos(3x)

Y = 2cos(4x)

Y = 4sin⁡(2x)

y = 4cos ?x

Sample Question 3
Write out the Sum and Difference Formulas (there are 6).

Sin(A+B)=sinAcosB+cosAsinB

Sin(A−B)=sinAcosB−cosAsinB

Cos(A+B)=cosAcosB−sinAsinB

Sample Question
Which identity is correct for sin(75°)?

Sin(45° - 30°) = sin45°cos30° + cos45°sin30°

Sin(60° + 15°) = sin60°cos15° - cos60°sin15°

Sin(45° + 30°) = sin45°cos30° + cos45°sin30°

Sin(90° - 15°) = sin15°
