但怎么能说级数convergent和divergent了呢?级数,根据上面的定义不就是一个数列的无穷多项依次加起来的一个和式吗?对于一个和式能说convergent和divergent吗?我看不如说一个级数has a sum or not,然后说其部分和组成的数列convergent和divergent似乎比较合适!说一个series converges to a limit L不如说这个series =...

Sum of Converging Series The sum of two converging series is also convergent. The same cannot be said with the sum of a converging and a diverging series. The sum of two diverging series is also not necessarily divergent. Answer and Explanatio...
Determine whether the series is convergent or divergent: {eq}\sum_{n=1}^{\infty } (-1)^n \frac{n^3 + 3}{n^3 + 1} {/eq}. Convergence/Divergence of series: We shall use the contrapositive of the condition that {eq}\sum_{1}^{\infty }a_{...
Determine whether the series is convergent or divergent. ∑n=1∞cos2nn2+1 Series Convergence: We will first dominate the series with another series and will verify the convergence of the dominant series by the integral test. In this way we are using the comparison ...

Is the series n=1∑∞tan−1(n1) absolutely convergent, conditionally convergent or divergent? https://socratic.org/questions/is-the-series-sum-n-1-infty-tan-1-1-n-absolutely-convergent-conditionally-conver Divergent Explanation: tan−1(n1) is that angle of ...
A geometric series diverges and does not have a sum to infinity if |r|≥1. If the terms get larger as the series progresses, the series diverges. The sum to infinity does not exist if |r|≥1. For example, the series is a divergent series because the terms get larger. The common ra...
