Java atan() method with Examples
The java.lang.Math.atan() returns the arc tangent of an angle in between -pi/2 through pi/2. If the argument is NaN, then the result is NaN.
Note:If the argument is zero, then the result is a zero with the same sign as the argument.
Syntax :
public static double atan(double a)
Parameter :
a : the value whose arc tangent is to be returned.
Return :
This method returns the arc tangent of the argument.
Example :To show working of java.lang.Math.atan() method.
import java.lang.Math;
class Gfg {
public static void main(String args[])
{
double a = Math.PI;
System.out.println(Math.atan(a));
double c = 344.0 ;
double d = 0.0 ;
double e = - 0.0 ;
double f = 1.5 ;
System.out.println(Math.atan(c));
System.out.println(Math.atan(d));
System.out.println(Math.atan(e));
System.out.println(Math.atan(f));
}
}
