Inverse Trigonometric Functions Quiz

What is the primary difference between regular and inverse trigonometric functions?

• Inverse functions are used to find side lengths.

• Inverse functions take a ratio as input and give an angle as output.

• Inverse functions take an angle as input and give a ratio as output.

• Inverse functions only work with right triangles.

If the cosine of an angle is 1/2, what is the angle using the inverse cosine function?

• 90 degrees

• 60 degrees

• 45 degrees

• 30 degrees

In a right triangle, if the side opposite angle B is 1 and the hypotenuse is 4, what is angle B using inverse sine?

• 30 degrees

• 14.47 degrees

• 45 degrees

• 60 degrees

When using inverse tangent to find an angle, why is it important to use the fraction form of the ratio?

• It ensures the angle is in radians.

• It provides a more precise answer.

• It is required by all calculators.

• It makes calculations faster.

If the opposite side is 3 and the adjacent side is 2, what is the angle using inverse tangent?

• 60 degrees

• 33.69 degrees

• 45 degrees

• 56.31 degrees
