public static double atan(double a)
Example
In the following code shows how to use Math.atan(double a) method.
// w w w. j ava2s . c o m
public class Main {
public static void main(String[] args) {
// get a variable x which is equal to PI/2
double x = Math.PI / 2;
// convert x to radians
x = Math.toRadians(x);
// get the arc tangent of x
System.out.println("Math.atan(" + x + ")" + Math.atan(x));
}
}
The code above generates the following result.
