Groovy - cos() method

---

---

The cos() method returns the cosine of the specified double value.

Syntax

double cos(double value)

Parameters

• value − A double data type.

Return Value

This method returns the cosine of the specified double value.

Example - Usage of cos() method for a positive double value

Following is an example of the usage of this method −

Example.groovy

class Example { 
   static void main(String[] args) { 
      double degrees = 45.0; 
      double radians = Math.toRadians(degrees);
	  
      System.out.format("The value of pi is %.4f%n", Math.PI);
      System.out.format("The cosine of %.1f degrees is %.4f%n", degrees, Math.cos(radians));
   }
}

Output

When we run the above program, we will get the following result −

The value of pi is 3.1416
The cosine of 45.0 degrees is 0.7071

Example - Usage of cos() method for zero double value

Following is an example of the usage of this method −

Example.groovy

class Example { 
   static void main(String[] args) { 
      double degrees = 0.0; 
      double radians = Math.toRadians(degrees);
	  
      System.out.format("The cosine of %.1f degrees is %.4f%n", degrees, Math.cos(radians));
   }
}

Output

When we run the above program, we will get the following result −

The cosine of 0.0 degrees is 1.0000

Example - Usage of cos() method for negative double value

Following is an example of the usage of this method −

Example.groovy

class Example { 
   static void main(String[] args) { 
      double degrees = -45.0; 
      double radians = Math.toRadians(degrees);
	  
      System.out.format("The cosine of %.1f degrees is %.4f%n", degrees, Math.cos(radians));
   }
}

Output

When we run the above program, we will get the following result −

The cosine of -45.0 degrees is 0.7071
