Below are sample questions representative of the exercises included on this worksheet and related TRIG.65 Evaluate inverse trigonometric functions using special values and approximations skill assessments:

Problem 1Difficulty: Mastery
Which expression equals pi over 2?
Aarctan(2) + arctan(2)
Barccos(0.8) - arcsin(0.8)
Carcsin(0.8) - arccos(0.8)
Darccos(0.8) + arcsin(0.8)
Solution & Explanation:For any x in [-1,1], arcsin(x) + arccos(x) = pi/2 because the angles are complementary. With x=0.8, choice D equals pi/2.
Problem 2Difficulty: Mastery
Evaluate: arctan(-4.2). Give the angle in degrees, nearest tenth.
Solution & Explanation:Compute theta = arctan(-4.2) and convert to degrees. The principal value is between -90 and 90 degrees. Round to the nearest tenth.
Problem 3Difficulty: Mastery
If arcsin(x) = -pi over 3, what is x?
Solution & Explanation:Apply sine to both sides: x = sin(-pi/3). Since sin(-pi/3)=-sin(pi/3)=-sqrt(3)/2, x=-sqrt(3)/2.
