Java Math.cos(double a)
Syntax
Math.cos(double a) has the following syntax.
public static double cos(double a)
Example
In the following code shows how to use Math.cos(double a) method.
//w w w . java 2 s . c o m
public class Main {
public static void main(String[] args) {
double x = 45.0;
double y = 180.0;
// convert them to radians
x = Math.toRadians(x);
y = Math.toRadians(y);
// calculate their cosine
System.out.println("Math.cos(" + x + ")=" + Math.cos(x));
System.out.println("Math.cos(" + y + ")=" + Math.cos(y));
}
}
The code above generates the following result.
