The method converts rectangular coordinates (x, y) to polar coordinate (r, theta) and returns theta.
double atan2(double y, double x)
Here is the detail of parameters −
X − X co-ordinate in double data type.
Y − Y co-ordinate in double data type.
This method returns theta from polar coordinate (r, theta).
public class Test { public static void main(String args[]) { double x = 45.0; double y = 30.0; System.out.println( Math.atan2(x, y) ); } }
This will produce the following result −
0.982793723247329
