Question

Assertion (A): Domain of y = cos⁻¹ (x) is [−1, 1].

Reason (R): The range of the principal value branch of y = cos⁻¹ (x) is [0, π] − `{pi/2}`.

Options

• Both Assertion (A) and Reason (R) are true and the Reason (R) is the correct explanation of the Assertion (A).

• Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of the Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Assertion (A) is true, but Reason (R) is false.

Explanation:

Range of cos⁻¹ x is [0, π].
