Java Math.sin()
方法返回指定double
值的正弦值。
語法
double sin(double d)
d
- double
資料型別。double
引數值的正弦值。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 sine of %.1f degrees is %.4f%n", degrees, Math.sin(radians));
}
}
執行上面範例程式碼,得到以下結果:
The value of pi is 3.1416
The sine of 45.0 degrees is 0.7071
