Re: Generating Functions
Hmmmm. So I guess the rocket will only get 1 / 5 of the way to the moon?
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Re: Generating Functions
Good enough.

Re: Generating Functions
With a better machine this Maxima code:
Code:
gf1(x):=ratexpand(ratsimp((gf(x))^1000)); sum(prime(i)*coeff(gf1(x),x^i),i,1,6000);
would get the needed answer.

Re: Generating Functions
You know that the lowest power in the expansion is 1000. The lowest prime in the expansion is 1009. What is the highest exponent in the expansion?

6000. 5987 is the largest prime below 6000.

Re: Generating Functions
Didn't you see it get used in the code above. It's the coeff() function.

Re: Generating Functions
I know that. But, why did you mention a function for coefficients?

Re: Generating Functions
It is one of the ways you can get an answer. In geogebra it is Coefficients[poly,variable], notice I cannot pick out anyone I want without further processing.

Re: Generating Functions
But it would have to sum all coefficients of prime-numbered powers if x, which is a lot of computing.
