The method Converts rectangular coordinates (x, y) to polar coordinate (r, theta) and returns theta.
Syntax
double atan2(double y, double x)
Parameters
- X – X co-ordinate in double data type
- Y – Y co-ordinate in double data type
Return Value
This method Returns theta from polar coordinate (r, theta).
Example
Following is an example of the usage of this method −
class Example {
static void main(String[] args){
double x = 45.0;
double y = 30.0;
System.out.println( Math.atan2(x, y) );
}
}
When we run the above program, we will get the following result −
0.982793723247329
