Question
Could y'all help me out with this? I know we are supposed to find an inequality, solve the inequality, then use that to find s_n, then find the error, but I'm not sure where to start or what to do.
![### Problem Set Instructions
Show all your work. In particular, you should clearly communicate your solution by providing arguments and statements that are complete, logically ordered, and use proper terminology and notation.
### Problem 1
You are given the infinite series:
\[
\sum_{k=1}^{\infty} \frac{(-1)^{k+1}}{k^6}
\]
#### Part (a)
Determine \( n \) so that \( s_n \approx \sum_{k=1}^{\infty} \frac{(-1)^{k+1}}{k^6} \) to within \( 10^{-4} \) of the actual sum of the series. (You may assume that this series converges by the Alternating Series Test.)
#### Part (b)
Compute \( s_n \) using the \( n \) you found in Part (a). Round your answer to 8 decimal places.
#### Part (c)
You are told that the actual sum of the series is \( \frac{31 \pi ^6}{30240} \). What is the actual error in this case? Give your answer to 8 decimal places.

### Detailed Explanation of Graphs and Diagrams
There are no graphs or diagrams present in the problem statement. The problem involves the series summation and convergence criteria calculations, which are purely algebraic in nature. If there were graphs, they should illustrate the convergence of the series or show the error bounds as a function of \( n \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff523a5f0-60bb-400a-95de-85afabbe42c1%2Ff9f7252f-25e5-4fe5-a850-dafbbb416e62%2F8e4fb6g.jpeg&w=3840&q=75)
