Math.Atan2() Method in C#
The Math.Atan2() method in C# is used to return the angle whose tangent is the quotient of two specified numbers.
Syntax
Following is the syntax −
public static double Atan2 (double val1, double val2);
Above, val1 is the y coordinate, whereas val2 is the x coordinate.
Example
Let us now see an example to implement Math.Atan2() method −
using System;
public class Demo {
public static void Main(){
double val1 = 3.0;
double val2 = 1.0;
double angle, radians;
radians = Math.Atan2(val1, val2);
angle = radians * (180/Math.PI);
Console.WriteLine("Result = "+angle);
}
}Output
This will produce the following output −
Result = 71.565051177078
Example
Let us see another example to implement Math.Atan2() method −
using System;
public class Demo {
public static void Main(){
double val1 = 0;
double val2 = 5;
double angle, radians;
radians = Math.Atan2(val1, val2);
angle = radians * (180/Math.PI);
Console.WriteLine("Result = "+angle);
}
}Output
This will produce the following output −
Result = 0
