The java.lang.Math.cosh() returns the hyperbolic cosine of a double value passed to it as argument. The hyperbolic cosine of any value a is defined as,
(ea + e-a)/2
where e is Euler’s number.
If the argument is NaN, then the result is NaN. If the argument is infinity then the result will be positive infinity. If the argument is zero, then the result is one.
public static double cosh(double a) Parameter : a : the value whose hyperbolic cosine is to be returned.
This method returns the hyperbolic cosine value of the argument.
Example 1 : To show working of java.lang.Math.cosh() method.
Example 2 : To show working of java.lang.Math.cosh() method when argument is NaN or infinity.
Infinity Infinity NaN
