Arcsin(x) Calculator
Enter a sine value between -1 and 1 to find the corresponding angle in degrees or radians.
θ = arcsin(x) or θ = sin⁻¹(x)
arcsin(0.5) = 30°
What is arcsin?
Arcsin (or inverse sine) is the inverse function of the sine. It is used to find the angle whose sine is a given number. For example, arcsin(0.5) is 30 degrees.
What is the range of arcsin?
The standard range of the arcsin function is from -90° to 90° (or -π/2 to π/2 radians).
What is the domain of arcsin?
The input value x for arcsin(x) must be between -1 and 1 inclusive. If you enter a value outside this range, the result is undefined.
