Examples
public class Test{
public static void main(String args[]){
double degrees = 45.0;
double radians = Math.toRadians(degrees);
System.out.format("pi 的值为 %.4f%n", Math.PI);
System.out.format("%.1f 度的余弦值为 %.4f%n", degrees, Math.cos(radians));
}
}
Compile the above program, the output is:
pi 的值为 3.1416 45.0 度的余弦值为 0.7071
