Re: Oh,Oh,Oh,merry analysis!!!

Yes, so keep that in mind because you were able to get a limit using this technique. By the way, many of gAr's series are possibly tackled through similar ideas.

Hi;

You do not see it yet but you are being introduced to generating functions. Some of gAr's can be attacked in that manner. Also, it is gAr's prerogative to assist you, it is his thread.

Okay and anyway you are supposed to work on problems that are too tough  for you. Ever seen my post to gAr about my top six?

Re: Oh,Oh,Oh,merry analysis!!!

hi bobbym

that kind of work is unreasonable because i don't have the mathematical 'tools' necessary for that kind of problems yet.

top six what?

Re: Oh,Oh,Oh,merry analysis!!!

I am supplying you with some of the tools. gAr is very strong in generating functions. It is only natural that he would use them, and summation of series is a by-product of them!

hi bobbym

are you sure your function is correct? the singularities do not even have a closed form!
