Questions & Answers

Q: What is the direct comparison test?

The direct comparison test in calculus 2 is a method used to determine the convergence or divergence of a series by comparing it to a known convergent or divergent series. It helps simplify the analysis of complex series.

Q: How do you choose a series to compare with in the direct comparison test?

To apply the direct comparison test, you need to choose a series that is easier to analyze and whose convergence is known. This series should have terms that are similar in size and behavior to the given series.

Q: Can the direct comparison test be used for series with 1/(n+3^n) terms?

Yes, the direct comparison test can be effectively applied to series with terms of 1/(n+3^n). By carefully selecting a convergent or divergent series for comparison, you can determine the convergence of the given series.

Q: What are the limitations of the direct comparison test?

The direct comparison test may not always provide conclusive results for all series, especially those with alternating terms or terms that do not have a clear pattern. In such cases, other convergence tests may be more suitable.
