StrictMath cosh() Method in Java

The java.lang.StrictMath.cosh() is an inbuilt method in Java which returns the hyperbolic cosine value of a given double argument.

  • The method returns NaN when the argument is NaN.
  • The method returns a positive infinity when the argument is infinity.
  • The method returns 1.0 when the given argument is 0.0.

Syntax :

public static double cosh(double num)

Parameters: The method accepts one parameter num of double type whose hyperbolic cosine value is to be returned.



Return Value : The method returns the hyperbolic cosine value of num.

Examples :

Input: num = 60.0
Output: 5.710036949078421E25

Input: num = 0.0
Output: 1.0
