Java.lang.Math.sin() Method

Advertisements


Description

The java.lang.Math.sin(double a) the trigonometric sine of an angle. Special cases:

  • If the argument is NaN or an infinity, then the result is NaN.

  • If the argument is zero, then the result is a zero with the same sign as the argument.

Declaration

Following is the declaration for java.lang.Math.sin() method

public static double sin(double a)

Parameters

  • a -- an angle, in radians.

Return Value

This method returns the sine of the argument.

Exception

  • NA

Example

The following example shows the usage of lang.Math.sin() method.

package com.tutorialspoint;

import java.lang.*;

public class MathDemo {

   public static void main(String[] args) {

      // get two double numbers numbers
      double x = 45;
      double y = -180;

      // convert them to radians
      x = Math.toRadians(x);
      y = Math.toRadians(y);

      // print the trigonometric sine for these doubles
      System.out.println("Math.sin(" + x + ")=" + Math.sin(x));
      System.out.println("Math.sin(" + y + ")=" + Math.sin(y));

   }
}

Let us compile and run the above program, this will produce the following result:

Math.sin(0.7853981633974483)=0.7071067811865475
Math.sin(-3.141592653589793)=-1.2246467991473532E-16
