# Java Math cosh() Function

## Java Math Class

Java Math class provides several methods to perform several operations on math calculations like max(), min(), sin(), cos(), round(), ceil(), floor(), abs(), cosh Function etc.
The java.lang.Math class contains various methods for performing basic numeric operations

Here, in the page we will discuss about the cosh Function of Math class in java.

## Java cosh Function :

Java Collection contains Math class and The class Math contains methods for performing basic and advance numeric operations such as the exponential, logarithm, square root, and trigonometric functions.
The cosh Function of math class in Java returns the hyperbolic cosine of the input angle. It is a static function so we can access it by using the Math class.

#### Syntax:

`Math.cosh(number);`

#### Return Type :

• For positive or negative number, It returns hyperbolic cosine value.
• For 0 as argument, It will return 1.
• For Infinity, It will return + Infinity.
• For NaN argument, this method will return NaN.

#### Example :

Run
```import java.util.*;

public class Main{
public static void main(String[] args){
// Initializing variables in Degree
int a = 0;
int b = 60;

// Using cosh Function
double cosha = Math.cosh(a);
double coshb = Math.cosh(b);

// Printing Values of Variables
System.out.println("Cos Value For angle a : " + cosha);
System.out.println("Cos Value For angle b : " + coshb);
}
}```
```Output:

Cos Value For angle a : 1.0
Cos Value For angle b : 5.710036949078421E25```

In the above Example, We had taken two variables with two different angles stored in them. we need to store the hyperbolic cosine values of the given angles in variables of double data type.

#### Example:

Run
```import java.util.*;

public class Main{
public static void main(String[] args){
// Initializing variables in Degree
int a = 0;
int b = 60;

// printing cosine values
System.out.println("Cos value of a : " + Math.cosh(radiana));
System.out.println("Cos value of b : " + Math.cosh(radianb));
}
}```
```Output:

Cos value of a : 1.0
Cos value of b : 1.600286857702386
```

In the above Example, We had converted the given angle into radians because  as per the official documentation of Java, the cos() method takes the angle as radians.
