Let x=(x1,x2,...,x n)∈n.Define a x-parking function to be a sequence(a1,a2,...,a n)of positive integers whose non-decreasing re- arrangement b1≤b2≤···≤b n satisfies b i≤x1+···+x i.Let P n(x)denote the number of x-parking functions.We discuss the enum...
设定义域为[x1,x2]的函数y=f(x)的图象为C,图象的两个端点分别为A、B,点O为坐标原点,点M是C上任意一点,向量OA=(x1,y1),OB=(x2,y2),OM=(x,y),满足x=λx1+(1-λ)x2(0<λ<1),又有向量ON=λOA+(1-λ)OB,现定义“函数y=f(x)在[x1,x2]上可在标准k下线性近似”是...
解：设三个点A、B、C的坐标分别为A(x1，y1)、B(x2，y2)、C(x3、y3)。那么A、B、C三点可围成一个三角形。AC与AB边的夹角为∠A。那么向量AB=(x2-x1，y2-y1)、向量AC=(x3-x1，y3-y1)。令向量AB=a，向量AC=b，则根据向量运算法则可得，|a·b|=|a|·|b|·|cosA|，那么cosA=...
在C#中相当于`IF(X AND(2 ^ Y))Then` 在C#中,相当于IF(X AND(2 ^ Y))Then的语句可以使用位运算符来实现。位运算符是一种操作二进制位的操作符,可以用来执行位级别的操作。在这个例子中,我们可以使用位运算符&来实现AND操作,使用位运算符^来实现XOR操作。 因此,可以使用以下代码来实现: 代码...
