Java.lang.StrictMath.asin() Method

---

Description

The java.lang.StrictMath.asin() method returns the arc sine of a value.The returned angle is in the range -pi/2 through pi/2. It include these cases −

• If the argument is NaN or its absolute value is greater than 1, 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.StrictMath.asin() method

public static double asin(double a)

Parameters

a − This is the value whose arc sine is to be returned.

Return Value

This method returns the arc sine of the argument.

Exception

NA

Example

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

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

   public static void main(String[] args) {

      double d1 = 0.90 , d2 = 5.00, d3 = 0;
   
      // returns the arc sine of a value
      double dAbsValue = StrictMath.asin(d1); 
      System.out.println("arc sine value of " + d1 + " = " + dAbsValue);

      // returns NaN if argument is NaN or its absolute value is greater than 1
      dAbsValue = StrictMath.asin(d2); 
      System.out.println("arc sine value of " + d2 + " = " + dAbsValue);

      // returns zero if the argument is 0
      dAbsValue = StrictMath.asin(d3); 
      System.out.println("arc sine value of " + d3 + " = " + dAbsValue);    
   }
}

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

arc sine value of 0.9 = 1.1197695149986342
arc sine value of 5.0 = NaN
arc sine value of 0.0 = 0.0
