[原创]数学图形　闲着无聊做的　请勿见笑！

没事闲着做的东西，请高手不要见笑：
#include <time.h>
#include <math.h>
#include <graphics.h>

main()
{
float i,x,y;
int gd=DETECT,gm;
initgraph(&gd,&gm,"");

for(i=0;i<660;i+=.01)
{
x=cos(i/5)*50+log(i+2)*sin(pow(i,0.5))*20+300;
y=sin(i/5)*50+log(i+2)*cos(pow(i,0.5))*20+230;
putpixel(x,y,12);
delay(100);
if(kbhit())exit(0);
}
getch();
}

无意间画出来的
感觉挺有意思的
不知道谁还有其他有意思的函数曲线
让大家分享一下！
