Sample Question 1
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°

Sample Question 2
Which identity is correct for cos(15°)?

Cos(60° - 45°) = cos60°cos45° - sin60°sin45°

Cos(30° - 15°) = cos30°cos15° - sin30°sin15°

Cos(90° - 75°) = cos75°

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