What is the difference between absolute and conditional convergence?[examples will be appreciated]
Here is a nice video:
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
The sequence is absolutely convergent iff both and converge.
It is conditionally convergent iff converges while diverges.
is absolutely convergent. We have and .
is conditionally convergent. We have while is divergent.
