Java Math.sin() method

The java.lang.Math.sin() is used to return the trigonometric sine of an angle. This method returns value between -1 to 1.

Syntax

Parameter

Return

If the argument is positive or negative number, this method will return the Sine value.
If the argument is NaN or infinity, this method will return NaN.
If the argument is zero, this method will return zero with the same sign as the argument.

Example 1

public class SinExample1
{
    public static void main(String[] args) 
    {
        double a = 60;
        // converting values to radians
        double b = Math.toRadians(a);
        System.out.println(Math.sin(b));
    }
}

Test it Now

Output:

0.8660254037844386

Example 2

public class SinExample2
{
    public static void main(String[] args) 
    {
        double a = 90;
        // converting values to radians
        double b = Math.toRadians(a);
        System.out.println(Math.sin(b));
    }
}

Test it Now

Output:

1.0

Example 3

public class SinExample3
{
    public static void main(String[] args) 
    {
        double a = 1.0/0;
        // converting values to radians
        double b = Math.toRadians(a);
        // Input infinity, Output NaN
        System.out.println(Math.sin(b));
    }
}

Test it Now

Output:

NaN
