The method returns the arctangent of the specified double value.
Syntax:
double atan(double d)
Parameters:
Here is the detail of parameters:
A double data types
Return Value :
Returns the arctangent of the specified double value.
Example:
public class Test{
public 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))));
}
}
This produces following result:
The value of pi is 3.1416
The arctangent of 1.0000 is 45.0000 degrees
