Java has a built-in Math class, defined in the java.lang package, which contains important functions to perform basic mathematical operations. The class has the cosh() method, which is used to compute a specified angle’s hyperbolic cosine.
public static double cosh(double angle);
The function takes in one single parameter, which is described below.
angle represents the double value corresponding to the angle in radians for which we have to find the hyperbolic cosine.The function returns the double value corresponding to the hyperbolic cosine of the angle.
If the value of angle is NaN.
If the value of angle is positive/negative infinity, then the return value is positive infinity.
To convert an angle measured in degrees to an equivalent angle measured in radians, we use can use the built-in
Math.toRadians(double angle_in_degrees)method.
