Question

state and prove Riemann's theorem for rearrangement of term of a series.​

Answer 1

Answer:

Theorem Riemann's Rearrangement Theorem Suppose ∑ an is a conditionally convergent series. Then for every real number s there is a rearrangement (bn) of (an) such that ∑ bn = s. ... This theorem makes it clear that conditionally convergent series are the only convergent series whose sum can be per- turbed by rearrangement.
