StrictMath acos() Method in Java

Last Updated : 28 Dec, 2022

The java.lang.StrictMath.acos() is an inbuilt method which returns cosine of a given argument and an angle. The angle which is returned within the range between 0.0 and pi. Note: If the absolute value of the argument is greater than 1 or the argument is itself a NaN then the result is also NaN. Syntax:

public static double acos(double num)

Parameters: The method accepts one parameter num which is of double type and refers the arc whose cosine is to be returned. Return Value: The method returns the arc cosine of the argument. Examples :

Input: num = 0.45 
Output: 1.1040309877476002

Input: num = 8.9
Output: NAN

Below programs illustrate the java.lang.StrictMath.acos() method: Program 1: For positive number

java

// Java program to illustrate the
// java.lang.StrictMath.acos()
import java.lang.*;

public class Geeks {

    public static void main(String[] args)
    {

        double num1 = 0.65, num2 = 6.30;

        // It returns the arc cosine of a value
        double acosValue = StrictMath.acos(num1);
        System.out.println(&quot;The arc cosine value of &quot;+
                             num1 + &quot; = &quot; + acosValue);

        acosValue = StrictMath.acos(num2);
        System.out.println(&quot;arc cosine value of &quot;+
                             num2 + &quot; = &quot; + acosValue);
    }
}

Output:

The arc cosine value of 0.65 = 0.863211890069541
arc cosine value of 6.3 = NaN

Program 2: For negative number.

java

// Java program to illustrate the
// java.lang.StrictMath.acos()
import java.lang.*;

public class Geeks {

    public static void main(String[] args)
    {

        double num1 = -0.65, num2 = -6.30;

        // It returns the arc cosine of a value
        double acosValue = StrictMath.acos(num1);
        System.out.println(&quot;The arc cosine value of &quot;+
                             num1 + &quot; = &quot; + acosValue);

        acosValue = StrictMath.acos(num2);
        System.out.println(&quot;arc cosine value of &quot;+
                             num2 + &quot; = &quot; + acosValue);
    }
}

Output:

The arc cosine value of -0.65 = 2.278380763520252
arc cosine value of -6.3 = NaN
