We’re really asking « what is the simplest, most basic angle where the secant equals 2? » As before, the answer is 60°. So sec-1 2 = 60° or sec-1 2 = π/3.

Where on the unit circle is sec equal to 2?

A secant is the inverse of a cosine (not a sine! Never a sine!), so when or (plus or minus 2π).

What is secant 2pi?

2π is a full rotation, so replace it with 0. The exact value of sec(0) is 1 .

What angle has a secant of 2?

The inverse function of the secant.Basic idea: To find sec-1 2, we ask « What angle is the secant equal to 2? » The answer is 60°. Therefore, we say sec-1 2 = 60°. In radians, this is sec-1 2 = π/3.

Is the secant equal to 1 on the cosine?

The secant of x is 1 divided by the cosine of x: seconds x = 1 because x and the cosecant of x is defined as 1 divided by the sine of x: csc x = 1 sin x .
