A.numberB.varietyC.sumD.series 相关知识点: 试题来源: 解析 B [精解] 从用法上可排除number和series,因为a number of和a series of都是接可数名词复数;a sum of一般是用来表示钱的数量;a variety of意思是“多种多样的,丰富的”,符合上下文。
Some Property of Random Dirichlet Series and B-Valued Random Dirichlet Series; 随机Dirichlet级数和B-值随机Dirichlet级数的一些性质 The number of turns of wire in the secondary coil is the same as the number of turns in the primary. 次级线圈的圈数和初线线圈圈数一样。
深入理解无穷级数和的定义(thesumoftheseries) Given an infinite sequence (a1, a2, a3, ...), a series is informally the form of adding all those terms together: a1 + a2 + a3 + ···. To emphasize that there are an infinite number of terms, a series is often called an infinite ...
, a series is informally the form of adding all those terms together: a1 + a2 + a3 + ···. To emphasize that there are an infinite number of terms, a series is often called an infinite series. 值得注意的是等式右边并不是左边的和,只是左边的缩写形式。 because when you start from ...
As you see, we defined the sum of a infinite series, this result seems not that naturally like 2 + 2 is computed out equal to 4,so is the definition give us the true sum of the infinite series?limn→∞Snhas a meaning that the number of the first n terms added up increases indefini...
The sum of an infinite geometric series is of the form: S=a11−r where a1 is the first term and r is the ratio whose absolute value is less than 1. We know that the second term is the first term multiplied by the ratio. In other words: a1⋅r=1a1=1r Thus, the sum is the...
The formula can be remembered by recalling that for even values of n, the sum can be rearranged to n/2 pairs each adding to (n+1). What is the sum of every natural number? The sum of every natural number is an infinite series which does not converge to a specific value. Adding ...
a series of numbers or quantities to be added up. an arithmetical problem to be solved, or such a problem worked out and having the various steps shown. the full amount, or the whole. the substance or gist of a matter, comprehensively or broadly viewed or expressed: ...
The summation formula of series sum from k=2 to ∞ f(k)■(k); 级数sum from k=2 to ∞f(k)(非汉字符号)(k)的求和公式 2. Krattenthaler obtained a general matrix inversions which unified most matrix inversions, and it was applied to derive a number of summation formulas of hypergeometri...
The sum of a list of length 0 is trivial; it is just zero. Second, on line 5 our function calls itself! This is the reason that we call the sum_of algorithm recursive. A recursive function is a function that calls itself.The diagram below shows the series of recursive calls that are...
