comment How many numbers are less than million such that their digits sum is $\le 19$?
@jj172 I think that this does answer one of the two questions that were asked. Actually to me it is a better answer than just "the coefficient of $x^{19}$ in the following expression". Don't feel discouraged because someone downvoted your answer, there are other people like me, who value computational answers like this one just as much as a more theoretical one.

comment How to show that $\int \limits_{-\infty}^{\infty} (t^2+1)^{-s} dt = \pi^{1/2} \frac{ \Gamma(s-1/2)}{\Gamma(s)}$
Thank you Lucian, it worked perfectly.
