Question

Which of the following is equivalent to sec⁻¹(0) expressed in radians?

A. π/2
B. π/4
C. π/3
D. π/6

Answer 1

The value of sec⁻¹(0) expressed in radians is undefined.

Step-by-step explanation:

The question is asking for the value of sec⁻¹(0) expressed in radians. The inverse secant function, sec⁻¹(x), gives the angle whose secant is equal to x.

Secant is the reciprocal of cosine, so sec⁻¹(0) is the angle whose cosine is equal to 1/0, which is undefined.

Therefore, there is no equivalent value of sec⁻¹(0) expressed in radians.
