C语言利用泰勒级数sin(X)

#include <stdio.h>#include <math.h>int main(){ int n=1,count=0; float x; double sum,term; printf("Input x: "); scanf("%f",&x); sum=x; //赋初始值 term=x; do{ term =-term*x*x/((n+1)*(n+2));//计算相应项 sum+=term; n+=2; count++; }while(fabs(term)>=1e-5); printf("sin(x)=%f,count=%dn",sum,count); return 0;}结果：Input x: 3sin(x)=0.141120,count=8
