C语言编写程序计算下列函数(精度为0.0001%) (1)sinx=x-x^3/3!+x^5/5!-x^7/7!+... 具体如图

  2 #include
  3 #define pi 3.14159265358
  4 int main()
  5 {
  6         double x,n=1;
  7         double s = 0,fn;
  8         printf("请输入度数：
");
  9         scanf("%lf",&x);
 10         x = x / 180 * pi;
 11         while(x > pi)
 12         {
 13                 x -= pi;
 14
 15         }
 16         fn = x;
 17         while(fabs(fn) > 0.0001)
 18         {
 19                 s += fn;
 20                 fn = -fn * x*x/(2*n*(2*n+1));
 21                 n++;
 22         }
 23         printf("sin(x) = %g
",s);
 24 }
