该方法返回指定双精度值的余弦值。
cos() - 语法
double cos(double d)
d - 此方法接受双精度数据类型的值。
cos() - 返回值
- 此方法返回指定双精度值的余弦值。
cos() - 示例
public class Test { public static void main(String args[]) { double degrees=45.0; double radians=Math.toRadians(degrees); System.out.format("The value of pi is %.4f%n", Math.PI); System.out.format("The cosine of %.1f degrees is %.4f%n", degrees, Math.cos(radians)); } }
这将产生以下输出-
The value of pi is 3.1416 The cosine of 45.0 degrees is 0.7071
