Java.lang.StrictMath.asin() Method

Advertisements


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
