考虑这样获得的交的区间,它们都是端点在集合 {a1,a2,… ,an,b1,b2,… ,bn}中的闭区间.注意到没有区间有一个公共的端点(否则,这个 端点至少属于三个S,矛盾).因此,所有的a和b都是不同的,这2n个端点每一个只用一 次,现在,我们考虑最小的a,不失一般性,可设为a1.因a和b是不同的,a1仅属于S, 但它...

Let a1,a2,…,a10 be an arithmetic progression (AP) with a common difference d=−3. The general term of the AP can be expressed as:ak=a+(k−1)d=a+(k−1)(−3)=a−3(k−1) Let b1,b2,…,b10 be a geometric progression (GP) with a common ratio r=2. The general ...
最后,关闭括号,完成let函数的输入。整个函数看起来应该是这样的:=let(name, A1, sum, A1:B1, name * sum)。 总结:通过使用let函数,我们可以将复杂的公式分解成多个简单的部分,每个部分都可以用变量来表示,从而使得整个公式更加清晰。此外,let函数也支持在变量定义中使用其他函数,提供了更高的灵活性。不过,需要...
