c语言编写三角函数
求sin的：参考下 #includestdio.h void main() { double x,a,b,sum=0; printf("请输入x的弧度值：\n"); scanf("%lf",x); int i,j,count=0; for(i=1;;i+=2) { count++; a=b=1; for(j=1;j=i;j++) { a*=x; b*=(double)j; } if(a/b0.0000001) break; else { if(count%2==0) sum-=a/b; else sum+=a/b; } } printf("%lf\n",sum); }
C语言函数求三角形，正方形还有园的面积
#include#definePI3.14159floaterea_round(floatr){//圆形面积returnr*r*PI;}floaterea_tri(floatd,floath){//三角形面积return0.5*d*h;}floaterea_rec(floata,floatb){//矩形面积returna*b;}intmain
用C语言实现三角函数及反三角函数怎么实现
#includestdio.h
#include math.h
void main()
{
double a,b,c,d;
scanf("%f,%f",b,d);
a=sin(b);/*这是三角函数*/
c=asin(d);/*这是反三角函数*/
printf("sin(b)=%f,asin(d)=%d",a,c);
}
其他三角函数如cos（x）什么的，可以直接用，前提有math.h的头文件
