C# has a built-in Math class which provides useful mathematical functions and operations. The class has the Atanh() function, which is used to compute the angle whose hyperbolic tangent comes out to be a specified number.
It is also known as the inverse hyperbolic tangent of a specified number.
public static double Atanh (double value);
Double type and represents the input value for which we have to find Atanh(). Its range must be:
Double: This value returns an angle Θ measured in radians and its type is Double. Its range is:
-∞ < θ < -1 (radians)
or
1 < θ < ∞ (radians)
It is true only for a valid range of value.
NaN: The function returns NaN type for an invalid range of value, i.e.,:
value < -1
or
value > 1
or
value = NaN
Multiply radians by 180/Math.PI to convert radians to degrees.
