Java Math - sin() Method



The java.lang.Math.sin() method returns trigonometric sine of an angle (angle should be in radians). In special cases it returns the following:

  • 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.

In the graph below, sin(x) vs x is plotted.

Sin Function

Syntax

public static double sin(double a)

Parameters

a Specify the angle in radian.

Return Value

Returns the trigonometric sine of an angle.

Exception

NA.

Example:

In the example below, sin() method is used to find out the trigonometric sine of an angle.

import java.lang.*;

public class MyClass {
 public static void main(String[] args) {
  System.out.println(Math.sin(Math.PI/6));   
  System.out.println(Math.sin(Math.PI/4));
  System.out.println(Math.sin(Math.PI/3));     
 }
}

The output of the above code will be:

0.49999999999999994
0.7071067811865475
0.8660254037844386
