Uniform convergence of a series.

Click For Summary
SUMMARY

The forum discussion centers on proving the uniform convergence of the series ∑n≥0 (-x)2n+1/(2n+1)! on the real line R. Participants suggest utilizing both Taylor series concepts and the Weierstrass M-test for this proof. A hint is provided to compare the series with the full series that includes even terms, specifically ∑ x2n+1/(2n+1)!. The goal is to demonstrate that the limit functions are continuous on R.

PREREQUISITES
  • Understanding of Taylor series expansions
  • Familiarity with uniform convergence concepts
  • Knowledge of the Weierstrass M-test
  • Basic calculus involving factorials and series
NEXT STEPS
  • Study the properties of Taylor series and their convergence
  • Learn about the Weierstrass M-test and its applications
  • Explore examples of uniform convergence in series
  • Investigate the relationship between uniform convergence and continuity
USEFUL FOR

Mathematics students, particularly those studying real analysis, and educators looking to deepen their understanding of series convergence and continuity in functions.

Homework Statement



Prove the series converges uniformly on R to functions which are continuous on R.

\sumn\geq0 (-x)2n+1/(2n+1)!

Homework Equations





The Attempt at a Solution


I'm having trouble actually figuring out what to use for this series..
It looks like a Taylor series but at the same time it looks like I could use W-M? Perhaps both?
Any hints are appreciated! :smile:

hi missavvy! :smile:

(have a sigma: ∑ and a ≥ :wink:)

hint: compare it to the full series (with the even numbers filled in) :wink:

(if it helps, try it with ∑ x2n+1/(2n+1)! first)
