# Java Math tan() 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() etc.
The java.lang.Math class contains various methods for performing basic numeric operations

Here, in the page we will discuss about the tan() Function in java.

## Java tan 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 tan Function of math class in Java returns the trigonometric tangent of the input angle. It is a static function so we can access it by using the Math class.

#### Syntax:

`Math.tan(number);`

#### Example :

Run
```import java.util.*;

public class Main{
public static void main(String[] args){
// Initializing variables in Degree
int a = 0;
int b = 45;

// Using tan Function
double tana = Math.tan(a);
double tanb = Math.tan(b);

// Printing Values of Variables
System.out.println("tan Value For angle a : " + tana);
System.out.println("tan Value For angle b : " + tanb);
}
}```
```Output:

tan Value For angle a : 0.0
tan Value For angle b : 1.6197751905438615
```

In the above Example, We had taken two variables with two different angles stored in them. we need to store the trigonometric tangent 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 tan values
System.out.println("tan value of a : " + Math.tan(radiana));
System.out.println("tan value of b : " + Math.tan(radianb));
}
}```
```Output:

tan value of a : 0.0
tan value of b : 1.7320508075688767```

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.
