Inverse Trigonometric Calculator
The Inverse Trigonometric Calculator finds the angle whose sine, cosine, or tangent equals a given value, in both degrees and radians. Choose the function and enter the value.
Formula
θ = arcsin(x), arccos(x) or arctan(x)
- arcsin and arccos require inputs between −1 and 1.
- Results are the principal values within each function's standard range.
