The method returns the cosine of the specified double value.
Syntax
double cos(double d)
Parameters
d – This method accepts a value of double data type.
Return Value
This method Returns the cosine of the specified double value.
Example
Following is an example of the usage of this method −
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));
}
}
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
