#define R(theta) 1-pow(cos(1*theta),1)

/*画心*/
void draw(int x,int y)

{r=R(theta);

xs=FNX(x1);ys=FNY(y1);
if(theta==0)moveto(xs,ys);else lineto(xs,ys);
}
}
/*画箭头*/

看到大家讨论对编程好不关系的话题,真的感到失望,如果你不是来学习的,请不要回复本贴,但也看到大家对于一些人生攻击的醒悟,
象 Momoass 能用公平的态度来对待大家的发言.
converse (创系) 也来劝大家说话和气.
相信他们这样的人才有成功的品质,非常热情,做事情就需要这样的人.
