设计一个程序计算并显示sin(x)

设计一个程序计算并显示sin(x),其中x=0, x=π/6
，π/4，π/3，π/2

#include <stdio.h>
#include <math.h>
int main()
{
    double PI  = 3.1415926;
    printf("sin(0) = %.2lf\n",sin(0));
    printf("sin(π/6) = %.2lf\n",sin(PI/6));
    printf("sin(π/4) = %.2lf\n",sin(PI/4));
    printf("sin(π/3) = %.2lf\n",sin(PI/3));
    printf("sin(π/2) = %.2lf\n",sin(PI/2));
    return 0;
}
