Arcsine Calculator

Calculate the arcsine (arcsin) of a value and get the angle in degrees, radians and gradians. Domain: −1 to 1.

What is Arcsin?

Arcsin (arc sine) is the inverse of the sine: given a value x, it returns the angle θ such that sin(θ) = x. The result is always in the interval [−90°, 90°].

Examples: arcsin(0) = 0°, arcsin(0.5) = 30°, arcsin(1) = 90°, arcsin(−1) = −90°.

Domain: −1 ≤ x ≤ 1. Values outside this range have no real arcsin.
