SUMMARY

The forum discussion focuses on evaluating the infinite summation of the series \(\sum_{n=0}^{\infty} \frac{1}{e^n}\). Participants highlight the connection to geometric series, specifically recognizing that this series can be expressed as \(\sum \left(\frac{1}{e}\right)^n\). The solution confirms that the series converges to \(\frac{1}{1 - \frac{1}{e}} = \frac{e}{e-1}\), providing a clear method for evaluation.

PREREQUISITES
  • Understanding of infinite series and convergence
  • Familiarity with geometric series
  • Basic knowledge of exponential functions
  • Ability to manipulate summation notation
NEXT STEPS
  • Study the properties of geometric series in detail
  • Learn about convergence tests for infinite series
  • Explore the concept of power series and their applications
  • Investigate the relationship between exponential functions and series
USEFUL FOR

Students and educators in mathematics, particularly those studying calculus and series convergence, as well as anyone seeking to deepen their understanding of infinite summations and geometric series.

The Attempt at a Solution



from what I've learn, i can calculate summation i in form

\sumna ,a is integer
or
\sum f(n+1)-f(n)

but how to make 1/e^n in any those form?
can give me any clue please
