I have this problem requiring me to show two infinite sums are equal but I can't seem to figure out how to do this. No matter what I try never give any results.
Hence my question is what approach should I use toward one of these question?
This is the question in question if it can help
Sorry, me again.
I also have the show a similar result for |x|>1
However using the power serie of
does not work in this case since it has as radius of convergence 1.
I must show if |x|>1 then
Unfortunately I am still as stuck and can't find a way to figure that one out even with the insight you gave me Olpag.
Anyone has an idea?
