The angle is calculated from trigonometric function. (Inverse trigonometric function)
When trigonometric function and the value that calculates are input and "Calculate the angle from trigonometric function" button is clicked, the inverse trigonometric function of the input value is calculated and the angle is displayed.
The angle is displayed by degree and radian.
Formula of inverse trigonometric function
