Question 7

## Transcription of Mathematical Content ### Problem 7 Evaluate the infinite series: \[ \sum_{n=2}^{\infty} \frac{n^2}{n^3 + 1} \] This problem involves analyzing the convergence or divergence of the series where the general term is given by the fraction \(\frac{n^2}{n^3 + 1}\). ### Problem 8 Evaluate the infinite series: \[ \sum_{n=1}^{\infty} n^2 e^{-n^3} \] This problem involves analyzing the convergence or divergence of the series where the general term involves the exponential function \(e^{-n^3}\) multiplied by \(n^2\). ### Explanation Both expressions represent infinite series, a concept fundamental in calculus for evaluating sums that extend indefinitely. The goal is to determine the behavior of these series—whether they converge to a finite value or diverge.

### Mathematical Concepts: Convergence and Divergence of Series #### Integral Representation: \[ \int_{1}^{6} f(x) \, dx \] #### Summations: \[ \sum_{i=1}^{5} a_i \] \[ \sum_{i=2}^{6} a_i \] ### Problem Statement: **Exercise 3-10:** Use the Integral Test to determine whether the series is convergent or divergent. --- ### Explanation: - **Integral Test:** This is a method used to determine the convergence or divergence of an infinite series by comparing it to an improper integral. If the integral converges, then the series converges; if the integral diverges, then the series diverges. - **Series and Summation Notation:** - \(\sum_{i=1}^{5} a_i \) represents the sum of a sequence from \(i=1\) to \(i=5\). - \(\sum_{i=2}^{6} a_i \) represents the sum of a sequence from \(i=2\) to \(i=6\). No graphs or diagrams are present in the image.
