C语言求三角函数f(x,y,z)=sin(x)/(sin(x-y)*sin(x-z))+sin(y)/(sin(y-x)*sin(y-z))+sin(z)/(sin(z-x)*sin(z-y))代码#include #include double fun(double x,double y,double z){double a,b,c,sum;a=sin(x)/(sin(x-y)*sin(x-z));b=sin(y)/(sin(y-x)*sin(y-z));c
C语言求三角函数
f(x,y,z)=sin(x)/(sin(x-y)*sin(x-z))+sin(y)/(sin(y-x)*sin(y-z))+sin(z)/(sin(z-x)*sin(z-y))
代码
#include
#include
double fun(double x,double y,double z)
{double a,b,c,sum;
a=sin(x)/(sin(x-y)*sin(x-z));
b=sin(y)/(sin(y-x)*sin(y-z));
c=sin(z)/(sin(z-x)*sin(z-y));
sum=a+b+c;
return sum;
}
void main()
{
double x,y,z,sum;
printf("请输入3个角度以,隔开:\n");
scanf("%lf,%lf,%lf",&x,&y,&z);
x=x*3.14/180;
y=y*3.14/180;
z=z*3.14/180;
fun(x,y,z);
printf("f(x,y,z)=%f\n",sum);
}
哪里错了?
