猜想:从圆内任何的一点A(该点不在圆周上),
画一条射线与圆周相交于B。
如果这条射线,以及其反向延长线不经过圆心,
一定有且仅有另一条从A开始的射线与圆周相交于另一点C,
满足线段AC的长度与线段AB相同。
证明:
不失一般性地假设圆心为O,圆的半径为r>0,OA线段长为a>0, AB线段长为b>0.
角OAB为t,-pi
根据三角形余弦定理,r,a,b,满足以下关系
r^2=a^2 + b^2 - 2abcos(t)
因为 a>0,b>0, 所以有
cos(t) = (r^2 - a^2)/(2ab) - b/(2a).
因为A在圆内, a^2 < r^2,
所以 cos(t)是 b的单调递减函数。
而cos(t) 在(-pi,0) 和[0,pi]两个子区间上分别是单调递增和单调递减函数。
也就是数在两个子区间上, cos(t)和是一一对应的。
任意另一条从A开始的射线,与圆交于另一点C,
如果AC的长度与线段AB相同,
那么角OAC的余弦必须与角OAB的余弦相同。
因为角OAB和OAC都在 (-pi,pi]... 阅读全帖 |

他不抽,说:我没想到你是个抽烟的女人。。。
我觉得不悦,噎了他一句:抽烟的女人怎么了?
他一点眼力见也没有,一边噼里啪啦地翻菜单一边细说吸烟的八大害处。。
越这样,我越一根接一根地抽我的,理都不理他
他还不识趣地说:我这样的男人没有任何嗜好,我是个好男人,谁嫁给我谁就一定会是
个幸福的女人。。
我特么强忍着等菜。。。
他点的神马野山鸡,我拿筷子戳过去硬邦邦地,好像是具死了很久的尸体。。
我只好闷头扒拉一碗米饭(是很小的那种碗)
因为无趣,而且没啥可吃的。。我就又叫服务员给来了一碗米饭
他自以为很幽默地说:你挺能吃啊?
