Understanding Arcsecant (sec⁻¹)

Arcsecant Definition:
The arcsecant function, written as sec⁻¹(x), is the inverse of the secant function. It determines the angle whose secant equals a given value.
θ = arcsec(x)

Domain: |x| ≥ 1 (since secant values are never between -1 and 1)
Range in radians: [0, π] excluding π/2
Range in degrees: [0°, 180°] excluding 90°

👉 In simple terms, arcsecant tells you the angle (in degrees or radians) that corresponds to a given secant value, including both positive and negative inputs.

Formula for Arcsecant

If sec(θ) = x, then:
θ = arcsec(x) = arccos(1/x)
Our Arcsecant Calculator applies this formula instantly, giving you accurate results without the need for manual steps.

Examples of Arcsecant Calculations

Using Decimal Values:

arcsec(2) = 60° = 1.047 rad → ✅ Result: 60° (1.047 rad)

arcsec(1.5) ≈ 48.19° = 0.841 rad → ✅ Result: 48.19° (0.841 rad)

arcsec(−3) ≈ 109.47° = 1.910 rad → ✅ Result: 109.47° (1.910 rad)

Using Fraction Values:

arcsec(5/3) ≈ 53.13° = 0.927 rad → ✅ Result: 53.13° (0.927 rad)

arcsec(7/4) ≈ 55.15° = 0.962 rad → ✅ Result: 55.15° (0.962 rad)

arcsec(−5/2) ≈ 113.57° = 1.982 rad → ✅ Result: 113.57° (1.982 rad)
