WebNov 22, 2024 · Now, we can consider x ≥ 1 ∨ x ≤ − 1. The necessary condition for the convergence is not satisfied, so the series diverges. In conclusion: ∑ n = 0 + ∞ ( n 2 + 1 n 2 + 2) n x n converges if and only x ∈ ( − 1, 1). ∑ n = 0 + ∞ ( n 2 + 1 n 2 + 2) n x n diverges if and only if x ≤ − 1 ∨ x ≥ 1. Share. WebMay 28, 2024 · The sum of a convergent geometric series can be calculated with the formula a ⁄ 1 – r, where “a” is the first term in the series and “r” is the number getting raised to a power. A geometric series converges if the r-value (i.e. the number getting raised to a power) is between -1 and 1 .

Oscillating. … WebDec 17, 2015 · But say we have an alternating sequence that oscillates towards the x-axis (converges to zero), e.g. $\frac{(-1)^{n}}{n}$, is it correct to say that the highest value and lowest value are the upper and lower bounds, respectively; because from what I can remember from calculus II, bounds didn't matter when it came to alternating series.

WebDoes ∑ n = 1 ∞ sin ( n π) / n 2 in C converge or diverge? My guess is that the series does not converge due to the periodicity of trigonometric functions but I can't be sure without figuring it out more formally. sin ( n π) = 0. Has the question been typed correctly? If so, the seris converges, and has sum 0, since every term is 0.
