Java Math tan() Function

July 20, 2023

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);

Definition of Parameters:

number The input or given numbers on which operation have to be performed.

Return Type :

True : This function returns the trigonometric tangent of the given angle.

NaN : if the given angle is NaN or infinity.

sqrt() Function

tanh() Function

todegrees() Function

tointexact() Function

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;

        // converting variables to radians
        double radiana = Math.toRadians(a);
        double radianb = Math.toRadians(b);

        // 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.
