买茶叶想到的哪个比较便宜 x1/y1 >x2/y2 x代表多少钱 y代表 多少克 无聊的试炼

茶叶1 128元     200克 茶叶2  330元    160克 当然这个哪个便宜 一眼就知道了,这里不过抛砖引玉 128元    330元 200克    160克 我们把价钱用x表示 多少克用y表示 x>0 y>0 已知 x1           x2 ~       >    ~ y1           y2 推导出x1y2>x2y1 可是为什么呢 假设 x2=x1*k1 y2=y1*k2 第一步 得到 x1       x1*k1 ~    >     ~ y…

hdu5794 A Simple Chess 容斥+Lucas 从(1,1)开始出发，每一步从(x1,y1)到达(x2,y2)满足(x2−x1)^2+(y2−y1)^2=5, x2>x1,y2>y1; 其实就是走日字。而且是往(n,m)方向走的日字。还有r个障碍物，障碍物不可以到达。求(1,1)到(n,m)的路径条数。

点(x1, y1)关于点(x0, y0)逆时针旋转a度后的坐标求解

问题描述: 求点(x1, y1)关于点(x0, y0)逆时针旋转a度后的坐标 思路: 1.首先可以将问题简化,先算点(x1, y1)关于源点逆时针旋转a度后的坐标,求出之后加上x0,y0即可. 2.关于源点旋转,用极坐标表示 设x1 = Rcos(θ), y1 = Rsin(θ),绕源点逆时针旋转β度后得到坐标(x2, y2)等于(Rcos(θ + β) , Rsin(θ + β)) 3.展开(Rcos(θ + β) , Rsin(θ + β)) 变成 x2 = Rcos(θ)cos(β) -…

现在有一张半径为r的圆桌，其中心位于(x,y)，现在他想把圆桌的中心移到(x1,y1)。每次移动一步，都必须在圆桌边缘固定一个点然后将圆桌绕这个点旋转。问最少需要移动几步。
