SUMMARY

The largest value of n for which the series $$\sum_{k=1}^\infty\frac{1}{k^n}$$ diverges is n = 1, as established by the integral test. This series is known as the harmonic series, which is a classic example of a divergent series. For values of n greater than 1, the series converges. Understanding this concept is crucial for analyzing the behavior of p-series in mathematical analysis.

PREREQUISITES
  • Understanding of series and convergence concepts
  • Familiarity with the integral test for convergence
  • Basic knowledge of harmonic series
  • Mathematical notation for summation and limits
NEXT STEPS
  • Study the integral test for convergence in detail
  • Explore p-series and their convergence criteria
  • Investigate other types of divergent series
  • Learn about the implications of series convergence in real analysis
USEFUL FOR

Mathematicians, students studying calculus or real analysis, and anyone interested in series convergence and divergence.

Hi all, is there any way to find what the largest value of n is such that $$\sum_{k=1}^\infty\frac{1}{k^n}$$ is divergent? I don't need an answer, I need an approach to the problem.

Integral test.

It is well known that if n = 1, the series is the harmonic series, which diverges.
