Greetings to all.
Just a quick question, probably something obvious, please bear with me Your patience is appreciated.
As part of solving a posted problem at math.SE it became necessary for me to compute the bivariate generating function
The correct answer (in fact a simple computation) is
When asked to compute this sum with the command shown, Maple produces
hypergeom(, , z) w
My question for you is, how does this represent the above answer that I computed manually? When I simplify the hypergeometric, Maple says
which would appear to be the wrong value. Could someone enlighten me regarding this discrepancy?
BTW there seems to be no tag "hypergeometric" and I don't have enough points to create it.
Best regards, Marko Riedel
