Java Math sin() method with Examples

// 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;
