transgalactic, using both line integral and double integral.
Now you have got this: , can you go ahead and find
I am sure NonCommAlg has a solution for , so can you please share with us?
Additional question is: What happens if is zero or negative. Is there a closed-form solution. I guess not, if so, how about if . I don't have a solution for this. If you have, can you please share.
Let me give an example showing how the previous equality is used to get the summation of an important series.
According to the equality,
Plug (3) into (4),
Multiply on both sides,
Finally, the series:
Some Special cases:
(10) (which is within everybody's expectation)
