The method returns the arctangent of the specified double value.
Syntax
double atan(double d)
Parameters
d – This method accepts a value of double data type.
Return Value
This method Returns the arctangent 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 arctangent of %.4f is %.4f degrees %n", Math.cos(radians),
Math.toDegrees(Math.atan(Math.sin(radians))));
}
}
When we run the above program, we will get the following result −
The value of pi is 3.1416 The arctangent of 0.7071 is 35.2644 degrees
