Java Math sin() Method

The sin() method of Java Math class returns the trigonometric sine of the specified angle.

Syntax:

public static double sin(double a)

Parameters:

The parameter ‘a’ represents an angle measured in radians.

Return Value:

The sin() method returns the sine of the argument.

• It returns zero with same sign as argument, if the argument passed is zero.
• It returns NaN, if the argument is NaN or infinity.

Example 1:

public class JavaMathSinExample1 {
    public static void main(String[] args) {
        double a=30;
        //return the sine trigonometric value for a
        System.out.println("sine value : "+Math.sin(a));
    }
}

Output:

sine value : -0.9880316240928618

Example 2:

public class JavaMathSinExample2 {
    public static void main(String[] args) {
        //return the sine value for Double.MIN_VALUE
        double a=Double.MIN_VALUE;
        System.out.println("Sine value for "+a+" = "+Math.sin(a));
    }
}

Output:

Sine value for 4.9E-324 = 4.9E-324

Example 3:

public class JavaMathSinExample3 {
    public static void main(String[] args) {
        // return an Sine value for PI
        double x = Math.PI;
        System.out.println("sine value for "+x+" = "+Math.sin(x));
    }
}

Output:

sine value for 3.141592653589793 = 1.2246467991473532E-16

Example 4:

public class JavaMathSinExample4 {
    public static void main(String[] args) {
       //returns zero with same sign as argument, if the argument passed is zero
        double x= 0d;
       System.out.println(Math.sin(x));
    }
}

Output:

0.0

Example 5:

public class JavaMathSinExample5 {
    public static void main(String[] args) {
       //returns NaN, if the argument passed is NaN or infinity
        double x= Double.NaN;
       System.out.println(Math.sin(x));
    }
}

Output:

NaN
