Inverse Trig Functions Calculator
Calculate angles using inverse trigonometric functions (arcsin, arccos, arctan).
Understanding Inverse Trigonometry
While normal trig functions take an angle and return a ratio, inverse trig functions (like arcsin) take a ratio and return the angle.
Frequently Asked Questions
Why do arcsin and arccos say "Undefined" for numbers > 1?
The hypotenuse is always the longest side of a right triangle, so the ratio of the opposite or adjacent side to the hypotenuse can never exceed 1. Thus, the domain of arcsin and arccos is limited to [-1, 1].
