Thank you. Out of interest, can it persuaded to give Binomial[a+b,a] as the output?

Of course. Maybe it would be nice to have a central wiki for these feature requests/bugs.

comment Using RSolve correctly
Thank you. You are quite right about the addendum (and I was wrong). I needed to have a way to specify that $i=k$. In terms of the initial condition $i==0$ although I see your point I don't think I agree. A perfectly good answer would be if $n \geq 1$ then $q[n]= e$ Gamma$[n,1]$, if $n =0$ then $q[n]=0$ wouldn't it?

comment Using RSolve correctly
Thanks. I am only interested in integer $i \geq 1$. I see that defining $q[0]$ implies to Mathematica that that it should provide a general solution that holds for $i=0$ as well which it can't do.

That seems very unhelpful of Mathematica to me. q[1]==1 gives a useful answer. How would you know which initial conditions it will be happy with?

Thank you. The problem with Minimize is that it doesn't do anything in my case.

accepted Why does Integrate return a solution that is not defined at a particular point when it actually is well defined at that point?
