acosh In Java, the Math.acosh() method computes the inverse hyperbolic cosine (arcosh) of a given number. It is available in Java 8 and later and requires the input x ≥ 1, as the function is undefined for values less than 1.
Example in Java:
java
Copy
Edit
public class Main {
public static void main(String[] args) {
double x = 2.0;
double result = Math.acosh(x);
System.out.println("acosh(" + x + " = " + result);
}
}
This program calculates acosh(2. and prints the result. The function follows the formula:
acosh
(
𝑥
)
=
ln
(
𝑥
+
𝑥
2
−
1
)
acosh(x)=ln(x+
x

−1
)
