C语言求SIN（X）求纠错
#include
int main()
{
double x,term;
double sin=0;
int sign=1,n=1;
scanf("%lf",&x);
term=(double)(sign*x)/n;
for(;term>=1e-5;n=n+2)
{
sin+=term;
term=sign*term*x*x/((n+1)(n+2));
sign=-sign;
}
printf("%lf",sin);
return 0;
}

在数学里乘号可以省略不写,类似(n+1)(n+2)这样.
但是程序里不能省略,所以
term=sign*term*x*x/((n+1)(n+2));
应该是：
term=sign*term*x*x/((n+1)*(n+2));
但是程序里不能省略,所以
term=sign*term*x*x/((n+1)(n+2));
应该是：
term=sign*term*x*x/((n+1)*(n+2));
