Hello.

I don't know how to calculate given coefficients in a given series. For example

coefficient next to

or a different one:

coefficient next to

Could you explain to me how it is done?

I'm sorry, it doesn't signify anything. I don't know why I put it there. It is simply a series . Is it all right now?

(x^3 + x^4 + ...) = x^9(1+x+x^2+...) = x^9/(1-x)^3. You can expand the denominator and use a Taylor series expansion and collect the coefficients.

You can try looking up Maclaurin series or Taylor series expansion.
