Inverse Trig Calculator — arcsin, arccos, arctan
Use this free inverse trig calculator to evaluate arcsin, arccos, and arctan. Enter a value and get the principal angle in both degrees and radians, with the function’s range and domain.
Principal ranges
arcsin returns angles in [−90°, 90°], arccos in [0°, 180°], and arctan in (−90°, 90°). arcsin and arccos require inputs between −1 and 1; arctan accepts any real number.

Frequently asked questions
Why must the input be between −1 and 1 for arcsin?
Sine and cosine only output values in [−1, 1], so their inverses are defined only there.
