Determine Convergence or Divergence

Click For Summary
SUMMARY

The series defined by the summation from n=2 to infinity of n/((n²+1)ln(n²+1)) is divergent. The integral test was applied, resulting in a positive infinity, confirming the divergence. The discussion emphasizes the validity of using the integral test for this series, highlighting the importance of understanding the conditions under which the test is applicable.

PREREQUISITES
  • Understanding of series convergence and divergence
  • Familiarity with the integral test for convergence
  • Knowledge of logarithmic functions and their properties
  • Basic calculus concepts, particularly limits and improper integrals
NEXT STEPS
  • Review the integral test for convergence in detail
  • Study examples of series that converge and diverge
  • Explore the comparison test for series convergence
  • Learn about other convergence tests such as the ratio test and root test
USEFUL FOR

Students studying calculus, particularly those focusing on series and convergence tests, as well as educators looking for examples of series divergence.

Homework Statement


Determine if the series the summation form n=2 to infinity of n/((n2+1)ln(n2+1)) is convergent or divergent.


Homework Equations





The Attempt at a Solution


I applied the integral test and got positive infinity, so I it diverges. But I want to know if I'm right. Am I right?

Right. But you might want to say a few words about why you think the series is valid to treat with the integral test.
