Divergence Test: Determining if a Series Converges or Diverges

WebOct 17, 2024 · both converge or both diverge (Figure 9.3.3 ). Although convergence of ∫ ∞ N f(x)dx implies convergence of the related series ∞ ∑ n = 1an, it does not imply that the value of the integral and the series are the same. They may be different, and often are. For example, ∞ ∑ n = 1(1 e)n = 1 e + (1 e)2 + (1 e)3 + ⋯. WebMay 27, 2024 · With this in mind, we want to show that if x < r, then ∞ ∑ n = 0annxn − 1 converges.
