Java.lang.StrictMath.sin() Method



The java.lang.StrictMath.sin() method returns the trigonometric sine of an angle.It include these 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.


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

public static double sin(double a)


  • a -- This is an angle, in radians.

Return Value

This method returns the sine of the argument.


  • NA


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

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

   public static void main(String[] args) {
   double d1 = (90*Math.PI)/180 , d2 = 0.0, d3 = (1.0/0.0) ;

   // returns the trigonometric sine of an angle 
   double sinValue = StrictMath.sin(d1); 
   System.out.println("Trigonometric sine of d1 = " + sinValue);
   sinValue = StrictMath.sin(d2); 
   System.out.println("Trigonometric sine of d2 = " + sinValue);
   sinValue = StrictMath.sin(d3); 
   System.out.println("Trigonometric sine of d3 = " + sinValue);

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

Trigonometric sine of d1 = 1.0
Trigonometric sine of d2 = 0.0
Trigonometric sine of d3 = NaN
