Java Math sin() method with Examples

Last Updated : 28 Jul, 2021

The java.lang.Math.sin() returns the trigonometry sine of an angle in between 0.0 and pi. If the argument is NaN or infinity, then the result is NaN. If the argument is zero, then the result is a zero with the same sign as the argument. The value returned will be between -1 and 1.

Syntax :

public static double sin(double a) ;

Parameter: The value whose sine is to be returned.

Return type: This method returns the sine value of the argument.

Implementation:

Here we will be proposing 2 examples one in which we will simply be showcasing the working of Math.sin() method of java.lang package method and secondary be edge case of the first example specific taken where argument is NaN or infinity.

Example 1

Java

// Java program to demonstrate working
// of java.lang.Math.sin() method
import java.lang.Math;

class Gfg {

    // driver code
    public static void main(String args[])
    {
        double a = 30;
        
        // converting values to radians
        double b = Math.toRadians(a);

        System.out.println(Math.sin(b));

        a = 45;
        
        // converting values to radians
        b = Math.toRadians(a);

        System.out.println(Math.sin(b));

        a = 60;
        
        // converting values to radians
        b = Math.toRadians(a);

        System.out.println(Math.sin(b));

        a = 90;
        
        // converting values to radians
        b = Math.toRadians(a);

        System.out.println(Math.sin(b));
    }
}

Output:

0.49999999999999994
0.7071067811865475
0.8660254037844386
1.0

Example 2

Java

// Java program to demonstrate working of Math.cos() method
// of java.lang package considering infinity case

// Importing classes from java.lang package
import java.lang.Math;

public class GFG {

    // Main driver method
    public static void main(String[] args)
    {

        double positiveInfinity = Double.POSITIVE_INFINITY;
        double negativeInfinity = Double.NEGATIVE_INFINITY;
        double nan = Double.NaN;
        double result;

        // Here argument is negative infinity,
        // output will be NaN
        result = Math.sin(negativeInfinity);
        System.out.println(result);

        // Here argument is positive infinity,
        // output will also be NaN
        result = Math.sin(positiveInfinity);
        System.out.println(result);

        // Here argument is NaN, output will be NaN
        result = Math.sin(nan);
        System.out.println(result);
    }
}

Output:

NaN
NaN
NaN
