Does the following series diverge or converge?
The Basics:
Let
be a formal infinite series. For any integer
, we define the
partial sum
of this series to be
; of course,
is a real number. If the sequence
converges to some limit
as
, then we say that the infinite series
is
convergent
, and
converges
to
; we also write
, and say that
is the
sum
of the infinite series
. If the partial sums
diverge
, then we say that the infinite series
is
divergent
.

i/n is the harmonic series which by intergral test is divergent and since divergent x cov. or div. is divergent, the series is divergent
