Estimated Sums in Infinite Series Problem

Click For Summary
SUMMARY

The discussion focuses on determining the number of terms required to achieve a specified accuracy for the infinite series Ʃ((-1)n)/(n(10n)) from n=1 to infinity, with an error threshold of |error| < 0.0001. Participants analyze the convergence of the series and the implications of the alternating series test. The conclusion emphasizes the necessity of calculating the terms until the absolute value of the next term is less than the error threshold, leading to a specific value of n for accurate summation.

PREREQUISITES
  • Understanding of infinite series and convergence criteria
  • Familiarity with the Alternating Series Test
  • Basic logarithmic properties and calculations
  • Knowledge of error analysis in numerical methods
NEXT STEPS
  • Study the Alternating Series Test in detail

Homework Statement


How many terms of the series do we need to add in order to find the sum to the indicated accuracy?
Ʃ((-1)n)/(n(10n)) from n=1 to infinity
|error| <.0001

I keep ending up with n=log(4)-log(n)
