Interval of convergence
The interval of convergence of a power
seriesis
the set of real numbers
x
for which the power series converges. In the extreme cases it can consists of
just the single point
p,
or it can be the set of all real numbers. Normally, it is an interval with
endpoints p
- r
and
p
+ r
where
r
is the radius of convergence of the
series. This interval may or may not contain either of the endpoints. So there
are four possibilities for the
interval:
