Java program to find the trigonometric tangent of an angle

Given an angle, we have to find the trigonometric tangent.
Submitted by Nidhi, on May 14, 2022

Problem statement

In this program, we will read a degree from the user using the Scanner class. Then we will find the trigonometric tangent of the given angle using the Math.tan() method and print the result.

Source Code

The source code to find the trigonometric tangent of an angle is given below. The given program is compiled and executed successfully.

// Java program to find the trigonometric tangent 
// of an angle

import java.util.*;

public class Main {
  public static void main(String[] args) {
    Scanner X = new Scanner(System.in);

    double degree = 0;

    System.out.print("Enter value in degree: ");
    degree = X.nextDouble();

    double rad = Math.toRadians(degree);

    System.out.print("Trigonometric tangent is: " + Math.tan(rad));
  }
}

Output

Enter value in degree: 30
Trigonometric tangent is: 0.5773502691896257

Explanation

In the above program, we imported the "java.util.*" package to use the Scanner class. Here, we created a public class Main that contains a main() method.

The main() method is the entry point for the program. Here, we created a variable degree of double type and read its value from the user using the nextDouble() method of the Scanner class. Then we converted the degree into radian using the Math.toRadians() method. After that, we found the trigonometric tangent using the Math.tan() method and printed the result.
